When we have a country that does not have corporations or any other large business entities, we can see how things work and proceed from there. Whatever you call an entity, corporation, llc, partnership, trust, you will have large business entities. You can get rid of the name but not large business organizations. BTW, individuals can have a monopoly. All it requires is one person controlling a product. The business entity structure they use to sell it is irrelevant. Are you also going to eliminate patents?
