Trying my best-
Thanx. I would note that do I think one could get schar even if there’s no one who can do the actual mitzva, as the gemara says if one studies the parsha of korbanos he gets schar as if he brought them, and it was talking at a time when it was impossible to bring korbanos. (And if I recall correctly, the Ramban explains that gemara this way in his introduction to Vayikra.)
