I think it important to distinguish between a free trade market, which should be largely unregulated. People should be able to buy and sell goods on an open market.
Capital markets, or ownership and control of wealth should be heavily regulated.
Huh, what's interesting about this is that you've basically arrived at a communist/anarchist idea on your own, but are describing it using Libertarian / Neoliberal Capitalist terminology. You're describing different types of property and saying that one type should be regulated and the other type shouldn't. Anti-capitalists distinguish between private property (the means of production privately owned and involved in an economic enterprise employing wage labor (i.e. factories, offices, farms)) and personal property (consumer goods or goods produced by an individual (i.e. books, art, jewelry)), and believe that the former should be abolished (or one could say regulated to require collective ownership of such property by the workers) while the latter should be unregulated or lightly regulated.
In short, you've independently come to the same conclusion that anarchists and communists came to, but are describing it in a strange way.
