biggest thing I've learned after working in the blockchain space for 2 years is that you don't even need a blockchain for many of the use cases that require immutability, permanence, and public access
i.e. simple data storage that doesn't require network-wide consensus for state validation of every single transaction or state transition can just be handled using a network optimized for just that
feels like the main people who push this idea or use case either don't understand the options available to them right now, or they are maxis or employees of some blockchain protocol they are pushing
I also did not really understand this, and maybe even the tech wasn't even ready until the past 12/18 months anyway, but just a general thought
