Any libertarian who doesn't have a plan to implement a Universal Basic Income in one form or another ultimately subscribes to an inherently contradictory philosophy. Liberty can only be realized when a person is not forced against their will to work in order to live.
I think on the level you're evaluating, ALL political philosophies (perhaps excluding solopsistic or nihilistic ones) some inherent contradictions. If you take them as "preference for slight to major changes from the status quo" rather than "a complete description of a perfect end-state", they get a lot more reasonable.
It's quite consistent to decry some of the more egregious current impositions on liberty without demanding the additional impositions on some that would further free some others.

Agreed, but my understanding is that most "libertarians" aren't trying to top-down maximize liberty or anything like that but are starting from state of nature and extrapolating some kind of social contract from there.
