this does not only happen in the US, taxation issues have been problematic for a long time, especially in my country, namely Indonesia, here crypto and NFTs are also taxed, the big problem is that it is not the NFTs that are taxed, but where the proceeds of the taxes go, only a small part is actually managed by the government for the state, some of the tax proceeds go into the wealth of government officials, through corruption and money laundering
I also come from Indonesia and I think this rule is 50:50 beneficial between the government and NFT owners, I'm sure we all know that some NFTs are used by some people to avoid taxes or money laundering even though with rules like this, new people those who want to try their luck at NFT will slowly back off and won't want to linger in NFT for long.
in some countries the discussion about imposing taxes on cryptocurrencies, NFT and WEB3 is still hotly debated, the government is just avoiding them it is obvious that they are too eyeing investors' money in this new technology.
