Being self-sufficient is an empty expression. To reach what standard? Living in caves and off the land, roaming like 100k years ago? Living similarly to how we live in the West in the present? The former is possible, and so are middle grounds hence me saying “you need to give up stuff”, but the latter is not.

Also, a professional is just another individual, possibly a member of the community, which I consider to be the smallest viable social unit for self sufficiency based on modern society. I believe in mutual aid. Capitalism’s hierarchy is based on ownership of resources and means of production, not skills, so your argument seems completely pointless to me. A society in which professionals exist is completely compatible with a classless society.

Also, I am not denying anything to anybody, I am just stating that learning certain things is unrealistic and this should not be the blueprint for a post-collapse society in my view because it is bound to fail in my opinion. If someone does manage to be fully self-sufficient, all power to them.

If you are actually a communist, being such a clearly not anarchist one, you need to consider putting your focus on arguing with the right-wing instead of your comrades.

I argue with whoever I want, including with leftists if this means building a common vision. And from what I can tell, my vision of what society should look like is completely different from yours.
