Aaq, i don’t have time at the moment to look up the igros, but you are agreeing that rav moshe writes that one who wants to be frummer on the shitah of the rambam in his time(our time all the more so) is a baal gaavah, thinking that he can make it in learning while doing other things.
You personally disagree and imagine that not working is some sort of existential threat.
I’ll take rav moshe’s leadership over your fantasies and chutzpah.
