I shouldn't think so as it is a cosmetic procedure. Your doctor shouldn't have been rude to you but he/she was right about one thing. A reputable cosmetic surgeon would not perform a tummy tuck on a 21yr old because you may want more children in the future. A tummy tuck would leave you with a lot less skin on your stomach and your belly button would be in a different place so you would have a lot of problems with over-stretched skin etc if you got pregnant again. Try not to let it get you down. I also have what I call a little kangaroo pouch but you only notice it in tight clothes. It's not the end of the world!
