I'll just quickly write something for you:

Capitalism is a part of liberalism. It applies liberal ideas, such as individual freedom, to economic issues, and thus advocates, for example, free trade.

What might we consider instead of freedom? Force.

Liberalism hates force. It wants all disputes to be resolved without the use of force. This leads to capitalist ideas (taking capitalism seriously) like that taxes are a use of force which should be improved on, that people don't have a right to bread (provided by someone else, who becomes in a small way their slave), etc...

The best argument against force comes from fallibilism. This was first discussed by the liberal philosopher William Godwin.

It is: in any disagreement, we might be wrong. The other guy might be right. Therefore, we should not impose our will on him. That isn't truth seeking, and truth seeking is needed because we don't know who is right and shouldn't assume it's us.

Force is inherently irrational because it assumes who is right based on the source of the ideas in question (or, if you prefer, denies the other guy has an idea, or something like that).

Why is it initiating force in particular that is bad, but defense is OK? Because defense does not sabotage truth seeking. The outcome already wasn't going to be decided based on reason when the first guy initiated force. Defense doesn't cause any new problem.

Capitalist values allow for all voluntary interaction, which is compatible with correcting our mistakes (does not require it, but allows it) and bans non-voluntary interaction in which some party is acting contrary to fallibilism.

Get the idea?
