I'm not sure why a court would have to 'allow' a company to enforce their own terms of service. The other way around would work: if a court finds that the terms of service are in violation of the law then an action can be reversed and terms can be revised.

It seems that courts are now being used as some sort of universal arbiter in every disagreement instead of using them for what they are for: decide on legal disputes. Not ever disagreement is a legal dispute but treating it like that makes society brittle and dystopian.
