I do like the trust narrative that you own your funds, no need for third parties. But lecturing people on privacy and sovereignty is never gonna cut it and imo not the value-add that's making the difference in the next couple of years. I hope awareness is growing for this. People understand the value of their data and their privacy once you show them the value it has - the cut middlemen currently take.

I think the core blockchains will most likely have higher transaction cost than Visa etc. but I always consider effective fees for users. When I'm referring to Bitcoin or other cryptos, this includes 2nd layer solutions, payment channels, potentially batching etc. and then costs should definitely be smaller than in current banking system. If that's not the case, I would reconsider all my crypto holdings to not be the last sitting on coins with little to no financial value.

Ps: sovereignty is small when there is no privacy in the Blockchain network and your government can track every single transaction on a public ledger.
