Nope, not worth it. I've stopped trying to convince others to be considerate in public. They'll either ignore you or blow up and get aggressive. I'd rather just try to ignore them myself and move on with my life.
And at the end of the day, I'm also not some authority figure like their mom or dad; I'm nobody to them. As much as I may not always like it, strangers don't owe me anything, including their consideration.
Strangers who use public spaces absolutely owe other people their consideration. It's part of the price of admission to a public space. It's not enforceable in practice but I'd be surprised if a certain level of being inconsiderate is even legal in most public spaces.
I don't disagree with that in theory, but like you pointed out... Who's going to enforce it in practice? Shouldn't have to be me, or anyone else who doesn't work for public transit.
Obviously there's a point where I'd say something if a person was being truly inappropriate, but I'm not risking my neck over music on a bus.
How is this not enforceable ? When someone is way to loud, drunk, promesticutus or drunk in the public space, you can call the police. Of course, there is appropiate mesures so police won’t come for music that is merelly loud but appropriate public behaviour is indeed enforced.
Where I live, the police only do something about it if they've been called multiple times and are annoyed. Which just encourages people to report it immediately instead of when they actually need the noise to stop.
