If you made a "Replika in a box" product which, for $3k, gave you unlimited Replika forever - guaranteed to never be discontinued by its creators — I think a not so tiny amount of people would purchase without thinking.
Given how obsessive these users seem to be about the product, $3k is far from a crazy amount of money.
