Exactly. If you just want to compete pricewise with a PS5 then a PC is not that hard to justify.
Say the generation will last you another 6 years. That's 432 euro for PS Plus Essential alone. Add the cost of the PS5 with a disk drive, that's another 460 euro. That's 892 euro for just the device itself. That'll get you a decently beefy PC that can do more than just gaming. Add on some piracy for the more morally ambiguous among us (and let's be honest, buying second hand also doesn't net the studio any profits) and you got a pretty comparable package without being locked into Sony's ecosystem.
