Intended actions matter. If you buy an expensive PC with the intent of video gaming, but then find that your interests shift, I have no problem with that. On the other hand, if you buy an expensive PC for the purpose of conspicuous consumption, to show off that you have bought it, then I'd be tilting my head at you. If you buy an expensive PC for the purpose of running it 24/7 to contribute to a system that is used primarily for speculation and that has enabled the rise of ransomware, then I have a large problem with it.
