Personally I think most of these sorts of things should have a 3 year warranty - but very few offer that. If you can’t handle the 1 year you need to plan on the reality in the US IMHO. This isn’t a Valve thing, its a USA thing. So ranting against Valve feels a little disengenuous. AFAIK there’s no competitior that’s better. Sony, Microsoft and Nintendo would say the same thing.

So - in the future buy with a card that extends the warranty by a year or buy an extended offering from the company or square or whatever, if you can’t self insure the 200 repair or 600 ish replacement costs.

Crypto is entirely an extremely expensive gambling system. It serves no actual explainable purpose for the vast majority of people. It’s trivially provable to be worse than existing alternatives in every way that isn’t scams and or money laundering.

All you really have to do with Zerotier is set up your network routing appropriately, and the end server would do reverse NAT, presumably via IPTables in most situations. Zerotier is just a virtual cable, everything else is the same as if you plugged in an ethernet cable between the two endpoints and you can run network services there just the same. Oh, you do have to enable the ZeroTier client to route public IPs for this to work.
