Trading between members of our species is part of what puts humans on top; it's another form of collaboration and some other species do it to a degree, but nowhere near the level that we do.

But the evolution from trading x for y to trading x for y governed by z ie introducing fiat currency is the issue.

Lightning trades and trading in general that produces nothing of value is the issue. It goes deeper, with the wealthy able to lobby and keep tax havens legal but I don't expect anything to change so why say anything more on it.
