I'm over-exaggerating, and I get the value when it's prohibitively expensive to write a TOS when it's essentially impossible to pre-emptively vet the legality of all possible clauses internationally as laws constantly change. But if the clause I wrote is technically valid, then what's the point? Just write a short phrase saying "We're going to do whatever we like, unless it's prohibited by law. Accept? Y/N"
