You, on the other hand, want rich people to hoard money.
The money is not really liberated, it is duplicated. When that money is put to use by lending it out, it literally creates new money out of nothing. There's money in your account and that same money is simultaneously lent out to others. This massively inflates the money supply, devaluing the currency. Printing of currency is insignificant next to the power of loans.
It's why things like startups are a low interest rate phenomenon and I wouldn't be surprised if it was the real reason why there were massive layoffs the second the US federal reserve raised interest rates: less loans means less free money for corporations to spend.

Of course. I too would like to be able to hoard money. Right now it would be irrational to do so since it would be inflated away to zero. We should all be able to simply amass wealth without having to perpetually chase investments to protect against the inflation caused by the sheer existence of those same investments.
There have been many attempts to ban lending. The result is always a fairly non-functioning economy.
For example, in most businesses, there is a disconnect between when the payroll must be paid, and accounts receivable get paid. This disconnect is taken care of by having a line of credit. You pay the payroll on credit, and pay off the credit when accounts receivable get paid.
