What has been built here has been practically miraculous in a lot of ways so I don't say this out of negativity but I get what you are saying and I have thought about a lot of what will make a blockchain generate revenue on a base level to perpetuate its existence into the future.
High fees is one way to do it and people constantly have to buy more to pay for gas. We know the issue. Terrible user experience.
Another way is to use part of the inflation to advertise and then generate ad revenue from viewers to pay for Additional advertisements and rain on users who meet certain criteria.

Another radical way is to launch memecoins on other chains and take the proceeds to pump out advertising and have additional resources to ramp up developement. The reason I don't just say buy up HIVE and burn it is because this ecosystem needs to grow in a time where free speech is in trouble.

Just using funds to buy HIVE and burn it is like taking a perfectly good car and crashing it for a YouTube video when someone could have used that car. I feel it is destructive.

What value would people get out of these memes on other chains? It's a fun and entertaining speculative investment.
