There are trade-offs here even if looked at purely from the worker's point of view. While it is probably strictly superior from that POV to have the exact same job with the exact same terms except without a non-compete, the inability to commit to a non-compete means that the equilibrium is shifted and the exact same job with the exact same terms likely wouldn't have existed in the first place.

Perhaps on the balance laws against non-competes are a good idea, but we should always be wary of claims of a free lunch.
