Good comment. Regarding this whole “zero transaction costs” issue, I can’t recommend weyl and posner’s “radical markets” enough. I’m right wing/classical liberal / leanbertarian or whatever you want to call a pro-market stance, but that book opened my eyes about the conflict between market mechanisms and the absolutist way our capitalist economy understands property. Once you see that absolute property rights are not pre-requisite to market dynamics, you can’t unsee it anymore.
