The largest rewards are going to people using their money to finance the creation of businesses that create products people want to buy? Yeah that makes sense to me.
You can say that what our system rewards is always derived from practical products the average person wants, but that doesn't seem like a useful way to think about things.
Nowhere did I suggest that the only way to become rich was to sell practical products. I will state that this is the primary way people acquire vast amounts of money and that whether people become rich via second order and abstract systems such as financing makes no difference. Ultimately the products would not exist without the financial system that was in place.
I don't understand what you mean by this? Is this a comment about the current startup funding phenomenon?
