Alimony shouldn’t exist.

But we should also have social safety nets in place such that alimony isn’t necessary.

The idea of alimony, though, has morphed over the years from allowing someone to, as you say, consider divorce without being trapped by finances, to replacing a stay-at-home spouse’s potential income had they not been the stay-at-home spouse. That change makes me pretty uncomfortable, especially the government stepping in requiring an ex spouse to pay what the other person might have made.
