Sorry for the slang. With a .22, recoil isn't likely to jar the scope enough for it to slip its adjustments internally. This is definitely a concern for centerfire rifles, however.
If the rifle is subjected to target duty only, and can be protected by a case and a covered shooting range, there may be less concern for features like a waterproof design and a turret design that will not get knocked out of adjustment by a bump.
However, if you ever take it in the field, it is quite likely to get a little wet and occasionally knocked around a little. A cheap scope won't survive that, but a well-made one will. Of course, there is no reason to expect the scope to be used to drive nails (although there was once an ad that showed that), but you should have confidence that the adjustments are as you set them.
I have read "horror stories" of cheap scopes that wouldn't hold zero just because they got left in the sun, so it isn't just G-forces that can make things move around.
As far as adjusting it every time you use it, I don't believe that is common practice for the short ranges involved with shooting a .22 rifle. The "dial your shot" crowd use scopes with target turrets (larger adjustment knobs that are typically not protected by weather caps and require no tools) and drop tables or ballistic calculators, wind gauges, humidity indicators, etc. and are shooting at extreme range with generally specialized calibers.
No, the idea for a .22 is to "sight in" at some known range, typically 50 yds. A .22 scope will have parallax designed for that distance, rather than something less useful like 100 yds. At closer ranges, the POI will be slightly higher than the POA, and at longer ranges the POI will be lower than the POA. And, since we're talking about the .22LR, the trajectory falls off quite quickly past 50 yds.
I understand there are scopes with ballistic reticles designed for .22LR, but I would consider these somewhat specialized and of limited utility.
Please understand that there is no magic price point where you will never have trouble with a scope. The higher priced ones tend to have better glass, and also better warranties. The lower priced ones tend to cause more trouble.
One thing I should have emphasized is the etched reticle. Targets for .22's are often quite small, and a thick reticle crosshair can obscure the target. Etched reticles can be made thinner than a wire-type, so that is something else that is a "good thing" to look for when shopping for a scope. Not a requirement, but a good thing.
(I have an old Leupold 1-4X on my .22 rifle, and I find the duplex reticle a little thick occasionally. It was a scope I moved from a .44 Magnum carbine, which it was ideally suited for. I suppose I'll have to cave in and actually buy a .22 scope.
