The freedom to conduct business is one of the core freedoms that Americans value. When Americans talk about freedom, they are including the freedom to form a business and create whatever business arrangements you want.
To American values, restrictions on how you do business are as infringing as restrictions on individual rights.
Along that same line of thinking, I think another historical American value/attitude is that a business is a person. More precisely, businesses only exist because individual people decide to take risks with their lives in the pursuit of whatever values they hold. Since they hold the risk privately, they get to hold the rewards privately.
That many people who take such risks value financial profit may be a concern to some, but is a non-concern to society as long as the marketplace is free of coercion.
Yep, one of our fundamental rights is the 'freedom of association', which the Supreme Court has ruled is protected by the first amendment. You are free to join together with others to pursue any lawful interest, and that includes commercial interests.
To American values, restrictions on how you do business are as infringing as restrictions on individual rights.
