A handful of anecdotes about hyperinflation do not amount to "plenty of historical data".

Inflation has the important role of decreasing the value of debt, which is something demurrage does not provide. Neither does a constant rate of 'inflation' via demurrage allow any kind of countercyclical policy.

"[inflationary monetary policy] constitutes the redistribution of wealth via inflation from the people to the banks"

Do you have any evidence for that claim?
