their influence on your decision making process does not imply free will
This means that nothing about free will is important in any decision making process, and thus free will is just a garbage concept that has no bearing or meaning in reality.
Even if there was such a thing as free will, it would be completely unimportant in decision making.
it is hard to imagine free will has nothing to do with why you don’t hold the tree morally responsible.
It doesn't, let's imagine free will separate from knowledge, reasoning, experience, etc. No amount of knowledge, reasoning, experience would prevent the tree from falling according to the laws of physics, that's why I don't hold the tree accountable. The tree has no knowledge, no reasoning, no experience, no morals, so, even if it could freely make the choice not to do it, because it doesn't have those things, it doesn't matter at all.
This is literally the opposite of true, it's true of highly heirarchical systems, not true of communism.
Socialist systems actually seek to decentralize power, meaning you need to be less reliant on people being saints... not more.
I don't see why you believe that at all.
