Thanks! I am personally quite a fan of Glen Weyl’s suggestion of a Common Ownership Self-Assessed Tax (COST), which could function as a fairly effective Land Value Tax.

The self-assessment part of it avoids the government having to invent a whole new bureaucracy to value everything, but the requirement to sell at the self-assessed price encourages an honest valuation. Much like the system of liturgy and antidosis in ancient Greece.
