It's a solution to the problem raised by the GP - how to fairly value IP.

This whole thread is about how many countries with land taxes don't similarly tax other assets like IP. Whether you think it's fair or not is another question - the blocker isn't fair valuation.

the solution to how to fairly value IP was provided by the owner, capital gains tax happens on sale of IP

capital gains does not happen on sale of land generally. These two things are obviously taxed differently because it is to the value of the government to do so, and the value of the government is supposed in many countries to somehow translate into a value for society.

Profits from property sales are often tax as CGT. It's only a select few jurisdictions that don't tax property sales, often with both CGTs and stamp duties.

The difference in how their taxed in the US is certainly not standard globally, nor is it likely to be optimal.

OK I did not know this about the U.S, having never owned property there.

Actually seems a bit weird to find a tax situation in the U.S that seems less beneficial to the person paying the tax than many other countries.
