Well, the first question is: how much money?

That question is usually answered by the people willing to take out commercial loans. Without the market supplying that function, you’d have to try and figure this out yourself centrally.

The second issue is that you really are spraying money evenly across the whole economy, effectively starving productive ventures of capital while at the same time endowing moribund ventures with it instead.

So it’s not quite an equivalent scheme, it has different benefits and costs.
