Apply this logic to any other crime and you'll see it's nonsensical.
"If no one cared about extrajudicial gangs roving the streets murdering people, the problem would be solved. After all, I wasn't murdered. That's simple logic right there"
You're right though. If no one cared about extrajudicial gangs roving the streets murdering people, then it wouldn't be a problem! I know it sounds crazy. But the argument is sound.
Let's put it this way. If everyone enjoyed extrajudicial gangs roving the streets murdering people, then it would be the opposite of a problem, wouldn't it? It would be a good thing.
A necessary requirement for a problem to be a problem is that we have to care about it, or at least the effects of it.
