Honestly I think instead of banning non-competes they should just make it a hard requirement that a non-compete must be X percentage(no smaller then 30 or 40%) of your salary per year for the non-compete. Which in my opinion is fair because the entire point of a non-compete because you know information that a competitor could use that would give them a financial advantage so it makes sense that they would have to pay for your silence that you're not going to give that information away. If a company is saying they're not willing to pay that money that means the information you know isn't enough for them to care about so a non-compete shouldn't be in place in the first place

Like I've seen it non-compete clauses for web designers, which I find absolutely fucking ridiculous because there is little nothing that a web developer should be able to learn about a company that would financially harm it by going elsewhere, it's clear in those cases that those complete clauses are exclusively there as a trap to try to make it so their devs don't leave. The arguments those companies use is that there's financial incentive for that compromise. So a "well yeah you can do non-competes but they must be paid" will more or less blow their entire argument out of the water.

Personally I think if something similar like that gets implemented, you'll see a lot of the jobs that currently have a non-compete as part of their onboarding process will magically lose that as a requirement
