Why I'm a compatibilist about free will I guess part of it is, it's not freedom from, it's freedom to. At any given moment, you have the freedom to do whatever range of things, and which one you actually do isn't just random nonsense, the one you do is determined by your desires and wants and, in general, the decision making machine that you are at that point.
There's no need to be free from causality for that.
And in some moments, you're not free to do a lot of things. If you're currently
leg-disabled, you're not free to run, but you're free to do other things
Ps my post is not excellent, it's unstructured, rambling, and I self admittedly have no idea how to express the ideas swimming around in my head.
