It isn’t ironic, it’s precisely how it’s supposed to work.

Laws take freedom (as in do whatever you want) from people and give it to other people so the total expected gains are bigger than without the law, pretending that dishonest lawmakers don’t exist (false obviously). Also, all laws are bets on their outcomes and sometimes they go south.

I believe it had more to do with the fact that armed robbery is inherently dangerous than just protecting property.
