You don't understand value. There is no other explanation for why you can't seem to understand why people choose things you personally don't approve of.

We live in a world of scarce resources. You need to create at least as much value for others as you consume, but beyond that point you can choose to do whatever you want that doesn't infringe on the law or other people (well, you only need to worry about the law, but ethically you should think of others too). Some people just don't care about the things you value. Why is that such a problem for you?
