Unconstitutional doesn't mean much when it's being decided by a group of unaccountable people that weren't elected through democratic means. If SCOTUS says something is legal, it's legal. That's how the system is setup, nothing else really matters. They'll justify their decisions however they want but the material ends are the only things that matter.

SCOTUS has ruled many terrible things over the course of our nation's history (upheld slavery, said slaves weren't people, equated money with speech, decided a presidential election while denying a recount, etc). Expecting them to somehow be better is a foolish task.

It's an institution that needs to be dismantled and rebuilt, where at minimum SCOTUS appointments should be elected by a national vote rather than letting an extreme minority decide (100 senators versus ~340,000,000 people).
