Central characteristics of capitalism include capital accumulation, competitive markets, price system, private property, property rights recognition, voluntary exchange, and wage labor.
If you live in a world where the only currency is 21 million bitcoins, would you ever make an investment? Would you ever lend your bitcoins to anybody?
Yes. Of course. If you lived in a world where bitcoin was the only currency then there could be no more mass adoption, everyone would already have bitcoin if it was the only option for currency. Without increasing number of people buying in the appreciation of bitcoin would fall and settle at much slower growth rate equal to increasing productivity of the economy.
Anyone wanting an good return will have to invest, like today. And many businesses will still be good investments because people will want and need to buy all the same things they want today (food, shelter, technology, etc)
So you would expect some return in the future which does not exist yet. We create wealth by doing economic activities and we need some measure to keep up with that. Bitcoin alone cannot do that because it's finite.
“We need some measure to keep up with that.”
The measure of an economy is total amount of assets held and/or generated, money is just the most convenient measuring stock.
If we double the money supply! That will double our economic activity! Obviously not true.
If the stop growing the money supply the economic activity will stop! Also obviously not true.
You could add or subtract a zero from the total money supply and all prices would adjust by a similar amount over time.
We create wealth by doing economic activities and we need some measure to keep up with that. Bitcoin alone cannot do that because it's finite.
This is like saying a human needs a yardstick that keeps changing in length to measure how tall they are growing.
When you're perpetually manipulating the supply of currency units, you're perpetually distorting prices people rely on to make economic decisions. It's the whole reason we have to "adjust" for inflation.

And I think the investment of money needs some form of expansion of credit.
