I'm not sure if your first point is a necessity for other perhaps good ideas.

They will either not make those notes or only do one batch due to it just being a novelty in it's current state.

For me it feels like 'blind entrepreneur + we want to ship + we need to ship for more funding'.

I would even like to support weird ideas if it wouldn't promote Bitcoin usage :-(

I think your second point is more interesting: why do you think this digital to analog transition will be a thing?

Even in Zimbabwe they already have 50% smartphones and those are only getting cheaper and cheaper and will continue to flood the market.

My future imagines a smartphone only world for everything. From money, to house and car key. Germany now allows your passport or driver license on your phone.

I think it will be much more interesting how we can make smartphone theft obsolete and phone recovery easy. Like how do I regain my phone's state when I loose it while traveling.
