Given the size of the european market and the median wealth in it, it won't. And if it did, someone else would quickly come to replace whoever left. Companies don't follow all those regulation for the fun of it, they do it because there is a lot more money to gain by doing it than by leaving that market. Also if other jurisdiction don't follow on that (or on GDPR too, while we're at it) I don't know how they explain it to their citizens. We european are not magical people, we just tend to remember a bit more that our govs and laws are there by our authority, and to serve our needs.
