Also, it’s impossible to disprove the existence of free will because it requires will to make a conclusion like that.
Free will is much closer to leprechauns (we still haven't mapped every forest!) on the truth spectrum than it is to cancer cures or fusion energy.
Considering that we as human beings don't get to decide what exactly we remember, recall, when we recall or how much we recall - that is memory. What we remember and what we forget. I point this out because it's not a conscious activity but also determines actions, greatly so even.
In the Monopoly example perhaps a property is bought bc its a favorite color or they remember winning before with it or its the one they kno their cousin wants. Whatever the personal reasons, there are reasons - nobody plays Monopoly with all logic and reason.
So we have limited circumstantial choices and predetermined biased assessments of those choices - both beyond our control.
What is free will in that context?
