Art is about expression. That expression doesn't have to be political in nature. You saying all art is political is just you trying to force politics into things regardless of whether it's there or not.
Do you think Animal Farm was just a funny book about clever pigs? Please, find me an example of a work of art with zero political message, engagement, involvement or stance.
Yes that book is political, that doesn't mean all books are political. And if you think Episode 4 is going to be political then you're in for a disappointment.
Capitalism is, in fact, political, yes. Consumerism is political. Products made, the choices made to buy them - entering into those systems even the choice of which brand to buy and why are all, on some level, political even if the choice comes down to mechanical specs vs. price or buying the cheapest most affordable one because one doesn't make enough money to buy a more preferable model. It doesn't have to be a grand statement to be political, but even the tactic engagement in the exchange of capital is a silent approval or acceptance.
Oh this lazy cop out. Again no, not everything is political even in this example. Toliets for example weren't made to make a political statement, nor do you make one by buying one. They were simply made as a clean way to dispose of our excrement. They're a necessity, not a political statement. And then there's another aspect your forgetting since you clearly think everything is purchased and comes from a store. What if I didn't buy those items? What if I made them out of necessity? Am I making a political statement when I make them? No, I'm just making these things because they're nice to have and can make my life easier and more comfortable.
Not everything is political. It only becomes political when pseudo-intellectuals like yourself try to make it political.
