Money supply management is important for price stability. There's no debt problem in fractional reserve banking. (Exactly because debt is slowly inflated away while real assets keep their value [as their nominal value increases].)

There's a tremendous amount of economic growth. And as long as there are places where we can put in some better technology, a more efficient process or organization, then growth will continue, and the money supply will have to grow, and it's currently done via bank-issued money, because it provides some risk management. (Which is the most important factor of money creation. This is why finance and insurance developed intertwined.)

Energy is one bottleneck, sure, but there's no serious slowdown of growth of electricity generation capacity for example. And GDP growth is decoupling from carbon intensity. (As it should as we started to invest a lot of our economic surplus to do so.)

...

The important thing to remember is that there's a balance between how much money is needed now and how much is issued to be paid back later, and obviously if the growth would be almost zero the interest rate would be almost zero too.

If growth slows down (the fiscal multiplier goes down, there are no more public things to do, no more houses to insulate to get a smaller HVAC bill, no unemployed person to teach skills who would then work) then need for money also goes down, as no one will offer to pay it back with interest, so interest rate will go down, so whatever amount of money we have (as debt) we can keep rolling it over.

And of course the central bank can always exchange debt money to non-debt money. (And every time it wants to increase the interest rate it used to do something similar, it sold assets [US Treasury bonds] which removed debt money from the system. And back in the 90s there was talk about how the US central bank will adapt if the US government starts to run surpluses permanently.)
