That is a problem, but you have P2P exchanges like https://localmonero.co/

I only buy Bitcoin in P2P exchages too

All else fails you can just buy another crypto, like Litecoin, and swap to get Monero, but here are other options

monero is easy to buy with fiat through LocalMonero or u can get it cheaper by buying something like usdc from a kyc exchange and using a swap service like trocador.app
