turbos that are put on from the factory have gone through all the smog certification through the factory so they're legal. If you're trying to install a turbo onto an engine that didn't come with one originally then you have to prove to CARB that your car will still pass smog with it on. That involves a lot of time, money, and paperwork (which is why most companies don't go through the headaches of certification for their turbo kits and label them "for off road use only")
IF you have the time and will to replace that engine every 2 years then yah, i guess that IS an option but i can't say that i'd recommend it. Swapping engines isn't exactly just: loosen a couple of bolts, lift, drop, tighten bolts. The wiring system must be sorted through so that everything works correctly (engine systems and chassis systems).
as far as uninstalling/reinstalling a turbo, once again, that's gonna be some work. for a turbo to function properly, the engine must be tuned correctly for it. Timing, fuel maps, etc. must all be callibrated for either the turbo or running NA.
unless you've been doing this your entire life or know EXACTLY what you're doing, swapping an engine or installing a turbo would require a couple of days down time at least, and that would mean EVERYTIME you have to switch back and forth. . .
