Is forced taxation necessary to raise revenue?

[DC Al Fine]

Yes.

Even if you went full libertarian by cutting the welfare states, and used tolls and private industry to fulfill basic services like roads and garbage collection, you'd still have the free rider problem for stuff like justice and defense.

No, actually. Exhibit A is Hong Kong. It owns all the land in fee simple, except for one Anglican church. It leases it out on long term land leases, and derives 90% of its revenues from being a landlord.

Isn't that effectively a property tax?
