I agree that most meme coins are just flashy projects with no future that bet everything on a pump and fast cash-out, but at the same time, isn't everyone free to decided where to put his money? If somebody wants to invest in memecoins because he thinks he will get more money that way compared to traditional coins, why not let everyone make his choice?
If meme coins can ruin crypto after 15 years then we built a castle on sand!
