I think you're on the road to chess wisdom and also adopting the Sicilian yourself ! :-) I gave up the 1e4 as white and adopted 1...c5 against 1e4 in my OTB games and my grade rocketed....
I think the reason for the Sicilian's resilience is it's central pawn majority.
I have been frusterated through all my experiences playing against the sicilian defense, especially that pesky najdorf variation, i tried the futile morra gambit, the kan, but none actually work, then i read multiple books on theory and opening books on how to beat a sicilian system, but yet there hasnt been an answer..., but lately i've been thinking; why is the sicilian WITH PERFECT play from BOTH SIDES, always favor black: black controls all perpetual draws, and notable dynamic positions, but something else really bugs me about it:
Should not white ALWAYS atleast draw, with PERFECT play, lets think logically about this, starting with step 1, the person who moves first......, should not he/she always win or draw, does it really make sense for black to win, when white plays perfectly? this has really bugged me for the last week........
so my perfect example would be the sicilian najdorf, where black does get alot of the chances, which leads back to why?, i think it has to do with an innacuracy very early from white, we may not discover the answer to chess in the next 10 years, but i can tell you this about the sicilian najdorf: what we know as book/main line moves from white, cant be the BEST and PERFECT moves, if black gets so much play, now this may be a personal bias, but this is unacceptable to see black suceed (no racism intended) with such force, so i say to you again 2 things
shouldn't white get a draw/win EVERY single time WITH PERFECT play?
the sicilian najdorf: why does it favor black more than white?, i mean i know why, but shouldnt all chess games favor white more than black, with perfect play that is ;)
