The whole plot starts with the assumption that the pro-cop MCU wouldn't fall over themselves for a white vigilante kid.
Then the reason he wants to use Dr Strange to fix things is because his friends can't get into college. Mind you he has money and resources and the good will of the superhero team.
Then instead of figuring things out ahead of time about how the spell would work, Peter keeps amending the spell until it breaks the multiverse. Then Dr Strange asks him the above issue about using other options that didn't include brain washing.
Oh my god this movie is so dumb. Will update. Spoilers if you care
Edit because some people are salty:
I like the movie and just decided to write down the thoughts since I don't usually get to in a theater setting with a movie I'm interested in.
I'm home sick and figured doing a play by play with my thoughts would be a fun exercise for me. If this makes you think I don't want people to enjoy things, then you've got the wrong idea. Enjoy your slop!
It's just that amateur media criticism is my slop.
Aww sad visiting a grave
