> The issue is that if you want to make a browser in the EU, you have to be extremely serious about it.

The current browser vendors have made the web so complex that this is already the case regardless of what laws do or do not impose. It's simply too large a project to implement one for any non-serious project to succeed (as evidenced by the fact that we haven't got a new browser since... Chrome. Microsoft edge sort of I guess but that project was abandoned and they moved to chrome).
