Good point there. I believe the fluid unit is the ETH since something like this could exist on ETH easily. Or a layer 2 solution that won't require high fees for transaction.
This one is a bit extreme, I think LOL. But why not leveling the playing field when it comes to transfer of value? Why not making as many assets out there as possible into a fluid unit that can be easily moved? This is tokenization in a nutshell and these questions are rhetorical...but, yeah, you get my point.
Found this on Twitter in Swarm's account and wanted to share - love it!
