There is, for a number of reasons, but not least of which is fairness. If I get a dollar, then the size of the economy doubles, my purchasing power as a fraction of the total amount of economic activity doubles. This creates wealth inequality over time, too. Likely to the benefit of the same people.
I hear you re: Cantillion effect, though I'm sure that could be solved with a targeted tax.
Most importantly, philosophically, nobody owes you a risk-free return over time on your idle, un-invested capital. I can think of no justification for why your dollar should be worth more in the future than it is today. At best, I could see an argument for the same amount, though I think a little bit less to encourage investment is a totally reasonable place to draw the line.

You mean the industrial revolution? I'd say there were externalities that affected that. Counter-point, the great depression.
