I'd quibble with that. Capitalism is a choice, market dynamics are not. E.g. The Soviet Union successfully outlawed capitalism, and in response market dynamics made their country collapse.

Unregulated market dynamics also gave us child labor, slave trade, 12h work days, company scrip, companies ruling over governments, etc. A powerful engine without constraints is out of control.

England imposed the institution of slavery on the American colonies by means of their regulation of economic affairs. It didn't occur spontaneously from market dynamics, but was specifically provided for by (their) laws.

I don't think there's much meaning in saying the Soviets outlawed capitalism.

Capital continued to exist and there continued to be people who decided what got built and who received them. To me, that's private ownership. I mean, it's not like apple trees suddenly began bearing Ladas. If I wanted to acquire a field to occupy / farm, it was presumably controlled by someone, either an individual person or group of people. I don't see the difference in saying that in one situation my neighbor owns the field as personal real estate, versus whatever terminology the soviets used for why I can't just take it.

> there continued to be people who decided what got built

The main distinction with capitalism is that the people who decide what gets built are private individuals in competition with each other, and incentivised by profit to meet the demands of consumers.

In communism the people who decide what gets built are part of a single central authority with no competitors and no profit motive. That system doesn't work, which is why it collapsed.
