I'm also Bronze. Been down here for a while, but haven't seen quite the awful things you're describing. If someone gets mad at me (as a jungler) for clearing a wave in front of tower, it's because I didn't realize they were trying to either freeze it or set up a slow push.
Those other strategies work well, but usually best to do them with people on voice comms. In general, being able to set up lane pressure properly so your opponent has to do certain things that impact either them or the rest of their team is the best way to win if you're in a potential carry role.
This season has been mostly support for me, so I'm a little bit out of practice, but minion management is huge, and towers are a decently large part of that.
Also, one other thing that's important to remember: When you take a tower, it allows your opponent to farm further back in their lane, which means they're better protected from ganks, because your jungler has to go through their entire jungle to get to them.
