A hindsight solution for rationalists to have reduced the setup costs of buying bitcoin would have been either to have had a Rationalist mining pool or arrange to have a few people buy in bulk and serve as points of distribution within the community.

This suggests that if a future opportunity appears to be worth the risk of investment, but has some barrier to entry that is individually costly but collectively trivial, we ought to work first to eliminate that barrier to entry, and then allow the community to evaluate more dispassionately on risk and return alone.
