It might look like this, but thinking about it, I guess it's still useful in reducing unwanted interactions. People are lazy, and thus adding even a little friction can help a lot in preventing them from doing stalkering, spreading hate etc.
I.e. of course it's possible to login with another user, find the one who blocked you, make a screenshot or something and then quote it or perform any other interaction in your main account. But it's obviously not very easy.
So I'm sure it worked as a solution to reduce negative interactions on the platform. However, Musk doesn't want reducing these, his goal is spreading chaos and forcing his narratives, so the decision totally makes sense for him.
