There's no setup aside from installing Steam
No setup? Driver updates? Who’s installing Windows? Does the controller use Bluetooth or a dongle? How would people know to install Steam? Does everyone have a wireless keyboard and mouse? What if they only have a DisplayPort cable? Do they have the correct HDMI cord for their GPU and TV?
A PS5 comes with everything needed in the box. Console, correct HDMI cord, compatible controller,USC cable, power cord. Plug it all in, push the power button. Controller pairs automatically when plugged in. No need to even make an account you could just quickly skip everything and put a game disk on the drive to play something without internet connection.
The PS5 requires the simplest setup. PC requires a lot more technical knowledge than you’re willing to admit.
