It’s not arbitrary. It’s defined by one’s relation to the means of production. This is capitalism in a nutshell.

You're confounding stuff for no reason. There is absolutely nothing wrong with enjoying the profits of your work, which naturally including the return on investment in a company you started and put together from nothing.

There is a big difference between the product of one’s work and the profits of one’s work. The latter is a curious notion.

A fundamental component of capitalism is private ownership of means of production, which allows a few people to profit from the product of other people’s labor.

Of course. That's why you should face the fact that if no one puts in the money and the legwork to jump-start the company, there is no taxes to be made nor there is profit to be distributed.
