I'm regularly frustrated by the subtle hubris of completeness that underlies so many scientific assertions.
I don't think science is to blame for that, but the oversimplified reporting of it. No serious scientist assumes completeness.
So when I buy a car in the EU instead of having the factory built radio, are they going to have 3rd pardy radios installed in it as well?
If someone made a case out of it, then probably yes. Tied selling is not allowed in most and probably all EU countries if it restricts competition. The remedy would of course not be that the other radios are installed but that you can choose another without a penalty. Does this count as a car analogy, b.t.w.?
