What made you think I thought the US isn’t authoritarian?
Authoritarian means the government deciding what people can do or say beyond preventing actual harm to others, or causing harm to their subjects to promote the government’s interest to the detriment of the people.
Overthrowing other governments is imperialism, not authoritarianism - I’d define thr latter as largely internal, exceptions being eg. Singapore’s laws applying to Singaporean citizens and residents even when they’re outside of Singapore.
Why not just tax based on the number of homes, isn’t that a better idea?
If someone owns three £10M mansions, they’re potentially depriving two families of homes by way of scarsity, but frankly if you can afford a £10M mansion is it really an issue, as you’re not being deprived of a home?
If they instead own one £10M mansion and forty £200k flats/terraces, they’re potentially depriving forty families of homes and so should probably be charged twenty times as much to dissuade people from buying up the cheapest homes.
