Nobody is forcing you to use bitcoin, and I doubt the community is forced either. If you don't wanna use it then you can move one, and tried to compete with the bitcoin chain. Old or young doesn't matter in crypto, or if you want that to count, then factoring the security of the network must be included too.

Simply because something started earlier than everyone, doesn't mean it's no longer good. Take gold or fiat for example, they're really 'old' compared to bitcoin.
