Yes freedom to choose what the sellers choose to sell which is determined by what is most profitable. Those things can include many things that are not in any way optimal from the perspective of the consumer. For instance fatty addictive foods. Sure you get to decide, but go to a grocery store. Most of the things there are garbage. Why? Well they are profitable to sell. They are addictive. They are cheap to produce so you can get a high margin. They are loaded with salt, sugar, carbs. They are made of corn. That's a parable for the whole economy.

People only produce profitable things, and that profit has to be significant, i.e. 3x for many food items. So you get a few corporation with billion dollar budgets that dominate the market with variations of the same thing, 100s of kinds of potato chips or whatever. And shut out variety, health and so on. You have choice to buy, but the seller has the choice to sell you whatever and destroy smaller competitors through competition and limit variety. Those shelves cost a lot of money and only the most profitable things stay on them, that's by design.

You can not compete with these guys because they have an economy of scale and you will no matter how hard you try achieve the same level of efficiencies to have any significant impact on the market. And even if you do, they will copy you or buy you out and then slowly turn whatever you were trying to do in the profit objective, corrupting it.
