Whatever you presume to be "we" is irrelevant.
Are you admitting that that laws of physics and chemistry control your thoughts, words and actions?
You are using the word 'control' in a bizarre way here. The brain is an evolved control system, so it is far more correct to say that we are in control ourselves. It also makes more sense because it's true that we can do as we like.
However, even if we accept your weird use of words, this is just another
fallacy (silly, avoidable mistake in logic) called an
appeal to consequences. Reality is under no obligation to be as you'd like it to be.
And you're also ignoring the fact that your proposed alternative is
impossible. For reasons I've explained endless times, even a non-material mind would have to operate over time and would be just as 'controlled' by the past as a purely material brain. The logic is inescapable, regardless.
Appeal to consequences is yet another fallacy that you could avoid if you could be arsed to learn anything about logical arguments. Why won't you?
What are you afraid of?
