What's wrong with eloping?

my boyfriend and I have been together for almost four years. I am 27, he's 28. We both work full time, but I'm the only who graduated college with a 4 year degree. my parents have never met him, but they dont approve because he didnt graduate college. I have a really strict old fashion asian mom. Ive decided that since no one really wants to attend a wedding if we had one, that maybe we should elope. Is that a bad idea?
