Yes, I'm conflating "BLM movement" and "individual Americans who want to help BLM achieve its goals" because isn't it the same thing.
No? I want to help BLM achieve its goals, but "launch a nationwide discussion" and "come to a consensus policy" are not actions I can personally take. If I post policy proposals on Facebook it seems unlikely to me that many people will read or be influenced by them; it also seems unlikely that they would be better than many other policy ideas already out there. If you actually do think that lack of policy ideas is the most important bottleneck for BLM and that personal Facebook posts by non-experts is a promising way of addressing it then that's a possible answer, but if so I'd like to see your analysis for why you believe that.
find solutions that both sides support
Note that at the national level this is inherently very difficult because for any proposal made by one party, the other party has an incentive to oppose it in order to deny the proposing party a victory (and the accompanying halo of strength and efficacy). But fortunately this is not necessarily a problem for at least some approaches to the police reform issue, because police are mostly controlled by state & city governments, and as noted many states and cities are under undisputed Democratic Party control, so the relevant politics are within rather than between parties.
defend shops from looters so people have more sympathy for your side
This seems to have already been done; reports of looting have become increasingly rare and polls report public sympathy for BLM is very high.
The question was not what the "BLM movement" should do, but what an individual Americans should do; your steps do not seem actionable for individuals. Your steps 1 and 2 also partly beg the question.
Additionally, assuming the support of all Democratic politicians is highly dubious; a number of cities that have been marked by highly visible abusive police behavior in recent weeks are already controlled by Democratic mayors and city councils, who in many cases have nonetheless refused to hold the police accountable. And support of 50% of the population (which BLM now has) is certainly not always enough to pass "whatever policy you want" absent coordinated organization and in the face of political inertia; for example marijuana legalization has had majority nationwide support for years but has no near-term prospect of passage at the federal level.
1) People are probably less likely to throw out stale bread if it's impossible to obtain fresh bread?
2) If the price of e.g. fish is less regulated but generally higher than that of bread, banning fresh bread would lead to a larger rise in the price of fish as more rich people switch to it, which would perhaps lead to fishermen working longer hours and catching more fish, helping make up the overall calorie shortfall from the poor harvest without increasing costs for poor people who could never afford fish in the first place. Whereas letting the price of bread itself rise would be more regressive?
3) Same as with fish but with meat from livestock, pushing tradeoffs in the direction of "slaughter this year" vs "keep fattening up for next year", which could be desirable if the wheat shortage is expected to be temporary, and might even decrease demand for wheat as livestock feed if that was a thing at the time?
Not sure how large any of these effects would be.
Since apparently some confirmed cases never develop symptoms (this study of Diamond Princess passengers estimates 18%), it seems the answer to your second question is "never"?
The world population is not infinite. If somebody moves to San Francisco that means lower demand and lower rents wherever they came from (and conversely many other US cities now have housing crises caused by exiles from San Francisco). The desirable cities should be allowed to expand until there is more than enough room for everybody (yes, everybody) who wants to live in them to live in them, at which point landlords will no longer have the leverage to keep rents high.
Next time I see somebody say "shoot for the moon so if you miss you'll land among the stars" I'm going to link them here.
You seem to be saying that you prefer general words that encompass many concepts rather than specific and more precise words.
I can believe that you meant something more specific and precise than "worrying sometimes makes things worse" when you said "secondary stressors", but your post failed to get any more precise distinction across, and if people used the term as jargon they wouldn't be using it for anything more precise than "worrying making things worse". (Less sure about the motivation vs "tactile ambition" example since I don't know of any decent framework for thinking about motivation.)
Yeah, Lesswrong sometimes feels a bit like a forum for a fad diet that has a compelling story for why it might work and seemed to have greatly helped a few people anecdotally, so the forum filled up with people excited about it, but it doesn't seem to actually work for most of them. Yet they keep coming back because their friends are on the forum now and because they don't want to admit failure.
FDIC doesn't insure safe deposit boxes. It does insure your checking account balance, but your bank still has to figure out somewhere with a nonnegative interest rate to put your money (since the FDIC insurance triggers only after the bank itself is wiped out). Or find a way to charge you enough fees to make your effective interest rate negative.
Yeah, ignoring the option to declare bankruptcy or foreclose, effectively bounding your downside, seems like a major gap in this analysis. Especially as many jurisdictions usually allow people to keep significant assets (primary residence, 401ks) in bankruptcy. (Though on the other hand since 2005 US bankruptcy law obliges many filers to accept "repayment plans" for some fraction of what they owe, so it's not quite "discharging your debt for free".) That said I guess the most common debt for people reading this post is probably nondischargeable student debt; it makes sense if it's mainly talking about that.
