In the case of video game consoles that could be the case. It turned out that being able to run unapproved software results mainly in people playing pirated games. These security measures are reactive to the actions other people have taken. We already experimented with computing being the wild west where there was little to no security. It turned out that bad actors will abuse anything they can find. Even if it's not economical some attackers will still cause abuse.

There's always going to be a market for computers that can run unapproved software. I don't see that going away.
