This community's stance on physical media ownership?

I might be asking a rhetorical question here but I was curious as to the overall consensus on physical media. Do support it because, unlike streaming, media can't take away what you've payed for? or are you against because it's a waste of money when you can "acquire" it through "alternative means?" I'm also thinking about getting a 4K Blu Ray player for when my wife and I get a new place; preferably one that can also play self hosted media. What do you guys think?
