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.
