in fact, in my opinion, the main function of Kyc is to avoid fraudsters in the crypto world, but the more here I see the more complicated, even I have tried an exchange using Kyc, but it has always been rejected, even though it is in accordance with the previous list if many people are disappointed with the method.
I don't find submitting on the KYC and getting approve is a complicated thing as most of my exchanges accounts are KYC approved.
Maybe you just need to read and follow carefully the requirements, for exchange like Binance, they have a very simply KYC requirements so me and my partner are both verified, other exchange could be different but I don't use them much so I'd go with the one I always use.
