Well paying for an abortion isn't really an issue at the moment unless i'm missing something (you can just use cash? The issue here is insurance cover, but that doesn't change). Also I have tried to search for 'pay for an abortion with cryptocurrency' but can't find anything relevant on this happening in reality (other than people suggest it could possibly happen?).
How would paying in crypto avoid app store fees? Presumably you mean the Apple / Google App Stores, when Apple or Google will still want to take their 30%? How do you bypass that?
> purchasing digital assets like art
Who is using Crypto to purchase art? (Note: NFTs are not purchasing Art, you own some metadata that refers to a piece of art publicly hosted somewhere else). I can certinaly use my fiat currency to purchase both the rights to artworks, to purchase actual physical art pieces without having to jump through payment hoops, and even to purchase on-demand streaming of performance art. I cant really do any of that with Crypto without turning it back into regular fiat currency first (without searching out the tiny amount of places that accept crypto directly, but even then - whats the advantage to just paying in fiat?).
I mean I'm entirely unconvinced there is a compelling real use-case in anything listed here.
> ten years ago it was inconceivable to do these things with crypto, ten years from now it may be that these systems will continue to improve in terms of fees, privacy, scalability and user experience.
IMO if a technology is actually transformative, it will find a valid use case quicker than this. The only real use-cases I have seen seem to have been creating ponzi-schemes, effectively laundering money and speculative gambling on the price.
