can't kuri opening e3 as white

I used to play 1.c4 with e3 later on. It's not strange. In fact, it's done very, very well at top level. Starting with 1.e3 isn't that strange at all, so I wouldn't be in such a rush to say you're winning despite playing a bad opening. (you're playing a good opening)

Now, I play 1.a3 as white. I have a much more difficult time convincing anyone else to do it. I'm pretty sure a fourth of the blitz pool at my rating has blocked me at this point, which would explain why I'm having trouble finding games...

I am playing e3 because I am avoiding any theories and using my own prep to beat my opponents. And it's a pure disrespectful. In blitz it's not that disrespecting but in rapid it's so disrespectful. It's because nobody is stockfish, nobody knows how to play chess. That's a bad starting move if my opponent is cheating. Other than that, that is a good option, I gotta tell playing e3 and blocking your bishop, that is gangster😂🤣 . i am pretty confident I can beat everyone If I play good moves. I will laugh at my opponents when I beat them with that and when I lose, I'll have an excuse for my loss and I get less annoyed.

I don't know by what metric you're basing it off of, but e3 setups by and large are real openings and not really disrespectful at all. Many times, e3 systems score best at top level. Perhaps if you don't study much chess, you might think it's a disrespectful opening, but no.

E3 is the Can't Kruijs opening

Van't Kruijs opening is e3

This is a real opening

This tame move usually just transposes to systems where Black achieves easy equality.

E3 is not the best way to start a chess game
