Some like Doge can't. Quite a few coin holders like seeing millions of Dogecoins in their wallets and tipping $0.001 here and there. It's found its niche. Its just technically challenged and has been abused by day traders for a while now. Don't get me wrong, I've never touched Dogecoin, but their community seem to enjoy their billions of coins.
Otherwise, I think you are right with other coins with high supply, but a lot of those are purposeful for the 2% premine for the devs to dump.
