> Inevitably, companies would arise that don't sell your data, and charge a higher fee to compensate the loss in revenue.

I've been waiting for that to happen in just about every product category I have ever used since the rise of surveillance capitalism and it hasn't yet. It's a fantasy.

Companies will always make more money by charging you as much as you're willing to pay and then also selling your data and/or using it against you for the rest of your life. No company is going to leave that endless flow of money on the table and settle for charging you a slightly higher amount one time. The shareholders won't tolerate that.
