That’s part of the price of freedom. Tor is a browser that makes it hard to be tracked down, so people use it to facilitate illegal activities. Crypto is a currency that makes it hard to be tracked down, so the same occurs. While most of us use and support these services for legal activities, just to be free from corporate and government oppression, there will always be people who use them to be from legal consequences.
Sadly, making it easier to find people who do things like post CSAM in turn makes it easier to find people who want to watch Porn without supplying a government ID. (Still can’t believe my state of Virginia passed that law.)
