What else could memecoins be?

Ten years ago, two weeks before the Ethereum project was publicly announced, I published this post on Bitcoin magazine
 arguing that issuing coins could be a new way to fund important public projects. The thinking went: society needs ways to fund valuable large-scale projects, markets and institutions (both corporations and governments) are the main techniques that we have today, and both work in some cases and fail in others. Issuing new coins seems like a third class of large-scale funding technology, and it seems different enough from both markets and institutions that it would succeed and fail in different places - and so it could fill in some important gaps.

People who care about cancer research could hold, accept and trade AntiCancerCoin; people who care about saving the environment would hold and use ClimateCoin, and so forth. The coins that people choose to use would determine what causes get funded.
Today in 2024, a major topic of discussion in "the crypto space" appears to be memecoins. We have seen memecoins before, starting from Dogecoin back in 2015, and "dog coins" were a major topic during the 2020-21 season. This time, they are heating up again, but in a way that is making many people feel uneasy, because there isn't anything particularly new and interesting about the memecoins. In fact, often quite the opposite: apparently a bunch of Solana memecoins have recently been openly super-racist
. And even the non-racist memecoins often seem to just go up and down in price and contribute nothing of value in their wake.
And people are upset:

Even long-time Ethereum philosopher Polynya is very very unhappy

One answer to this conundrum is to shake our heads and virtue-signal about how much we are utterly abhorred by and stand against this stupidity. And to some extent, this is the correct thing to do. But at the same time, we can also ask another question: if people value having fun, and financialized games seem to at least sometimes provide that, then could there be a more positive-sum version of this whole concept?
