Where did I say it got food from the US (and other countries) by trading manufactured goods? How many Soviet manufactured goods do you remember seeing in Western countries?

What the Soviet Union actually "traded" for food was concessions on treaty issues like nuclear weapons. Which was particularly convenient for them since most of what they conceded was not actually verifiable, so the "concessions" amounted to making promises they had no intention of keeping, in exchange for actual stuff.

The point is, people had enough food to survive, which is the point I was addressing.

No, the point you were addressing was that the system in which the people lived was able to provide for them, which was not true of the Soviet Union. If the West had not agreed to play the USSR's con game of trading non-verifiable concessions for actual stuff for decades, the USSR would have collapsed a lot sooner than it did.
