To be in the realm of fair non-compete compensation needs to be total comp and not just base salary. In the US while not working you need to cover healthcare costs and many roles have a significant portion of comp from percentages of sales, bonuses, and other incentives. Just a base salary payment during a 6-12 month furlough would be a big pay cut for many.

There also likely needs to be some additional compensation for lost time in the market when skills are atrophying or new experience isn't being gained.

Non-competes have a place, but there needs to be tons of rules around their use, like only being available for specialized and other high paid roles. Something like 3x-4x median salary to be a position eligible for a company to even propose a non-compete.
