Perhaps we are judging too soon what taxless means. For a functional group of individuals to live together, let's say in an apartment, there must still be some collective activity to maintain the household and pay for common goods. Everyone otherwise works in their own self interest and would rather get the other person to lay while enjoying the outcome.

It might not be called tax but some form of funding mechanism is needed to pay for public goods, if not the society will soon crumble under its own weight due to poor maintenance and lack of public utilities.
