If instead of "selling" or "exchanging" those Euros, the purchasing power of those Euros may have changed as the result of inflation, PPP, used lamborghini prices, etc. The change in value depends on the change in value of what you have marked it to. Direct USD exchange, there's huge profits/loses because of the volatility of cryptocurrencies vs. USD. But NFTs...these become a kind of volatility cold storage. I'm not trying to mentally hack tax law, I'm suggesting that the law as described in an example by a journalist would show cryptocurrencies are not currencies, and now that the US is making enforcement a priority, they are collapsing the uncertainty bubble in which the whole market has operated. The invention of cryptocurrencies was a tax revolt to begin with, and it probably makes more sense to look at policy through this lens than any other.
