Afternoon Mossy! Have been following the farmers protests in the UK as well as other ones across Europe over the last few years. Taxes like that are called estate taxes here and as you stated, there are plenty of ways of getting around them with a good accountant.
I am set up as a S corporation and everything that I own in set up into different sub corporations and trusts
The main thing that surprised me the other day was the tax rates. 5% is an insane amount for property tax!
