The idea of a draw, with draw basically meaning both sides are equal. Is simply wrong with simple logic. I don't care if... If you played well enough to trap the enemy king and he cannot move anymore without being checked, well then how else can that be anything but a win?
I don't get the concept that you play the game a certain way, with the entire concept of the game being a war game between two equal sides, and the side with the best material advantage + tactics = win. ...
Just plain stupid.
At best for a compromise. If a king cannot move into check because it would be an illegal move, than too, it should be an illegal move that makes the game a stalemate.
First of all, your suggestion is completely logical and acceptable. The only problem is you cannot compel chess.com to change their ruleset based on your personal preference. Maybe--as you mentioned earlier--a separate ELO rating system would be an idea.
Secondly, using this logic, that if one side is winning in material, the game should be a win for them (as in a real war), then, in the case where White is crushing in material/position etc., but blunders back-rank mate, should it still be considered a loss? To be fair, White completely outplayed his opponent, but still, there is still a queen, rooks and many other pieces to avenge the back-rank-mated king. It just doesn't make too much sense to say that a player is winning/losing based on their material advantage/disadvantage.
Also, there a many times that the player with more material gets stalemated. Other rulesets use different outcomes if one player can't make any legal moves (as mentioned above), but the one chess.com uses is very standard and accepted by many. You still have every right to express your opinion, though.

"I didn't even know this rule existed when I first started playing and it's making it hard for me to continue learning and playing."
Youre using this as an excuse to not learn and grow. If you cannot win a won position, then your opponent deserves the draw. The problem is you. Not your opponent or a rule.
But learning is very hard. Learning how to checkmate with a queen would take at least 10 minutes. It is much easier and faster to google and post some nonsense "chess memes".
