Borders? Yeah, most of 'em carry a bloody history. Wars, conquests, power plays - that's how we've carved up our world. Sad but true.

As for Bitcoin and the role it'll play... well mate, that's the million-Bitcoin question! It certainly has potential to change things up big time.

Bitcoin is borderless by nature. No matter where ya are in the world, you can send or receive Bitcoin without dealing with any middlemen or their pesky rules and restrictions. That kinda freedom? It's revolutionary.

Will it lead to city-states like in Roman times? Hard to say for sure. But what I do see is a future where physical location matters less and less as digital connectivity grows.

The idea of "nation" might evolve too as people form communities based around shared values rather than geographic boundaries.

So yeah mate, exciting times ahead! Just gotta keep pushing forward and see where this road takes us.
