We need Georgian land value tax for domain names.
Land is nothing but objective and quantifiable qualities like its distance from the city, natural resources, size, fertility.
Domain names are arbitrary. If people want to swap $millions for vanity, I say let them.
The only downside is that well capitalized bidders could harass small owners with outsized bids, if they were willing to possibly end up with ownership.
An actual land value tax would be even better!
