I don't believe that there is 'no future'.
What you believe is irrelevant to how an argument works. To demonstrate that the future is fixed, your argument must work independent of the assumption that it does.

I am not, in fact, asserting the consequent, because I am not saying that you would go back from the future, I am saying that you would go back from now.
But that is exactly the same. By assuming that the present state existed, to be "the same as", in the past, you have assumed the fixity of the future. The future is a directed relation between two points of time; if one of these points is
past with respect to the other, then that other is
future with respect to the first.
The libertarian position about free will is not that the agent can perform
both actions
A and
not-A, it's that the agent can perform
either action
A or not-A. So it's not an objection to point out that at time one the agent performs a specific action, and that is all that your thought experiment could achieve, even if it could be constructed without begging the question.
