I'm not saying it's the best, I'm saying it's sufficient.

I'd rather have no warranty, bountiful parts availability, and lower prices instead of a great warranty, poor parts availability, and higher prices. I want to own things, not rent them, and an expensive warranty is closer to rental than ownership. However, I also think defects should be covered, so a short initial warranty is good (like 1-2 years for most things). I can get that with my credit card, so I don't need manufacturers to provide it.

In short, I want manufacturers to make things, not service them. I don't want Valve to fix my Steam Deck, I want it to be cheaper and for replacement parts to be cheaply available. Getting both means I'm paying more, since I'm subsidizing the warranty and support systems they need to provide.
