If people don't have to learn how to protect their data, if they don't understand what bitcoin does or have an idea about how it is achieved, then what's the point of it all?

I don't think it's reasonable to expect that everyone becomes a cypto expert and ideally the learning curve would be almost invisible, while I don't want the tech to become politicized/radicalized, I also don't want people just joining private and centralized networks just because someone called them a cryptocurrency and they didn't have the tools to question this.

A piece of paper saying that you own bitcoin means nothing, absolutely nothing, and it never will...even if the ETF gets approved in the future.

No keys, no money!
