Weird to premise an article on the assertion that blockchain devs suffer from a lack of...adversarial thinking? "How will this technology be used to harass and abuse people?" is a question that security engineers ask every single day!

> there is very little privacy available once your crypto wallet address is known, because every transaction is publicly visible, and attempts to obscure them often easily unobscured with chain analysis tools

Any good crypto wallet will generate a distinct address for each transaction. (Granted, chain analysis could help correlate addresses, but doing so requires a vastly larger effort and success is not guaranteed.)

> immutable social network content is horrifying given what people post themselves. Imagine if the cringy posts by a twelve-year-old were guaranteed to be available in perpetuity as soon as they were saved

Once your data is on my machine, it is out of your hands forever. This is a fundamental principle, and the alternative is surely more dystopian. Norms must change to accommodate what is a technological fact; the reason they haven't changed yet is because most social technology is still centralized. But people already understand that you can't un-send an email, for example. Why should the rest of the internet be different?
