And block people that use a bookmark or share the link via chat programs? I think almost no sites would do that.

They would if the users affected do not impact their bottom line. After all, the whole point of this is to keep out users who are not paying their 'fair share' via Google/Meta by proxy.

But also, the technical solution to bookmarks and small-scale sharing between friends is quite obvious. You don't need referrers to solve that problem.
