If a jurisdiction is at will employment – and there is no contract committing the employer to keep the employee employed, then non-competes should generally be banned.

And people really do need to distinguish a non-compete terms from non-disclosure terms, and terms regarding taking things like lists of customers/prospective customers. Numerous contracts from employers to prospective employees contain all of those terms, no just non-compete. What is legit is non-disclosure and similarly, not non-competes.

(Plus, of course, if no one can use non-competes, if your company isn’t willing to train entry level employees, odds are, no one else is, either, and there will be no new employees entering the profession until somebody wises up. As noted, this is the same rules for everyone.)
