what security? the only ad blockers youtube blocks are the intrusive/shady ones that could actually compromise your security, in fact, AdBlock was the one popping out windows asking for donations some time ago.
that being said, i doubt anyone here is asking people to turn off adblockers, just use a normal instead of the absurd trickery you've done to block pre-roll ads. ublock origin doesn't block pre-roll ads and that's exactly why youtube allows it, i haven't had a single "turn off your adblocker" screen in different 5 computers.
