I didn't say it was a protocol flaw. It's a flaw in our attempt to just rebuild what we already know, instead of putting more thought into the workflows.

My point is the opposite:

The protocol and other innovations make a lot of complicated stuff bizarrely easy, and we haven't even begun to scratch the surface of it because we've been caught up in rebuilding stuff we're used to.

There are entire use cases that are only feasible, now, and they suddenly became feasible for everyone, everywhere, at almost no cost.
