Before I address any of your points, I feel I don't understand what you're saying here:
The issue I take with lamenting that "some things shouldn't be commercialized" is the egoism involved in thinking one ideology should be able to make that decision.
So I want to paraphrase it to see if I understand it.
"It is egotistical to think that one ideology (the one I ascribe to) should make a (any) decision that might affect others."
If this is not what you are saying, please correct me!
(This comes from a "How to" article about how to argue with someone. As in, how to logically, coherently, respectfully argue with someone, not the kind of internet arguing that is so ubiquitous today. Their first bullet point was that you have to paraphrase what the other person is saying before you present a rebuttal, to make sure you understand their point. I really like this, because I think a lot of ugly internet arguing arises from simple misunderstandings of meaning.)
