You're just going to Galapagos your economy. Consumers won't put up with high prices and inferior goods. Unless you want to restrict internet/information access so your consumers don't know what they are missing out on.

Humans are weird.
I dunno. Consumers put up with a lot. Why can't I buy a cheap Chinese EV again?
