People starting to trust each-other instead of blindly following the rule of the land was what transformed feudalism into ‘capitalism’/free market/democracy.
That came to be when populations happening to inhabit a certain area morphed into nations = people developed enough understanding about their fellow countryman as to trust them.
Nowadays capital no longer signifies trust but a mere pile of money and democracy has devolved into a mere ritual.
This is why nationalism has degenerated from ‘I know/trust you so let’s do business together’ into ‘I’m afraid of everybody else so I need you to guard my back’.
