If meme tokens are ruining everything, then the fault lays in the core of the platform itself, as the whole idea of permissionless transactions is not to control people. If you set people free, they act as they wish, not how we or you wish. It's only freedom of the people we can blame for that. No one is facing any consequences for acting immaturely or stupid, because that's build on the core of the design. I can't see why they would go away as they have just grown since start of dogecoin. So as long there are people there will be some abstract meme tokens and imho we just embrace them as a sign of freedom.
It might be frustrating, but freedom will bring in the worst and the best of people, and because majority of people are quite stupid, stupidity will overcome reason any day.
Blockchain developers should increase on-chain transaction capacity to prevent "meme" coins from clogging the network. Or they could force everyone to move to a L2 network for complete peace of mind (like how Ethereum is doing today). The problem with "meme" coins is that most of them are simple tokens living on existing blockchain networks. This tells us that developers are none other than "script kiddies" or amateur coders without any Blockchain experience. The only exception is Dogecoin because it has its own chain. If all of the "memes" had their own chains, crypto land would be a better place.
I hope to see more quality over quantity in the crypto industry soon. Projects that actually have a real use case and aren't driven by hype/speculation. It's only been 15 years since the inception of BTC, anyways. Crypto/Blockchain tech is just starting to blossom. Maybe it will mature sometime in the future?
Enforcing something like that would mean some serious changes to L1 that most people wouldn't agree with.
It also most likely would make everything even more centralized, as there would need to be a consensus where people would need to agree about very specific definition of a "meme" token.
That would create more tokens that would just game the system and change themselves just enough to bypass the definition. They would add smallest amount of functionality that fooled most of the people, and teams wouldn't call them meme tokens, even if they would be identical to them. Concept of meme is very vague, and it seems like a lost fight to me. Some of them would seem like a meme from the outside, because meme sells, and at the same time good experimental tech under the hood. And at the end, chain would end up just full of copycat tokens that have basically identical code.
With freedom comes also insufferable stupidity, and that's going to be enforced by at least 50% of population. So i wouldn't put any trust on stakers voting for coins that get to be in L1 either. Even if they wouldn't want those tokens in L1, there would be a problem with stakers selling their votes when new meme tokens wanted in L1.
