It's a game, not a simulator. I mean, how would I handle fireballs then? Would I roll for lung damage due to the targets breathing in hot air (enforcing realistic consequences), or would I just disallow the spell because magic is not realistic? Or if the enemy gets shot by an arrow, would I roll for organ damage?

And of course you have to account for the fun of all players. Would it be fun for the wrestler player to take out any humanoid in two turns? Probably. Possibly. Would it also be fun for the archer and the swordsman who still have to play by the normal game rules instead of the power fantasy of a "hurr durr wrestling is da ultimate martial art" player, and have to actually use their attacks to overcome the enemies' AC and whittle down their HP? Doubtful. What's the point of having them around if the wrestler can just choke everything because that's the part of combat that the DM suddenly starts simulating realistically?

Either enemies can survive a dozen arrows, being roasted alive in their armor for a minute, being stabbed with a rapier a lot, etc... and they can last long enough versus a wrestler that just choking them doesn't become the dominant strategy, or they can be choked out in a realistic timeframe but they can also be instakilled by an arrow or a sword.

If you only take one element of the game and turn it "realistically" OP while the rest remain fantasy, you're liable to fuck up the whole game for everybody else. Now there could be a merit in playing "dark and gritty, all damage is super lethal" games but then that's not really D&D anymore, something like Mörk Borg might be better for it.
