I know what you're getting at.
I was commenting specifically because I hate sloppy language and sloppy thought: there's just no meaningful sense in which "a particular kind of contract becoming non-enforceable" simplifies into "not being able to sign a particular kind of contract"; the latter implies some kind of intrusive intervention -- a noncompete gestapo slapping pen-from-hand should you try to sign such a contract -- which clearly wouldn't be the case under the proposal.
