Indeed I still have problems with step 8, and want to get back to that. But I want to do it when it when you're not exhausted arguming other points... Part of the problem, is that I already agree with the reversal at step 7, so in some sense step 8 is redundant for me. There may be an issue with the interpretation of the 323 principle. I have no problems with the removal of a register that is never physically used in the calculation of a consious computation. The nuances arise when we consider Everett's many-minds picture. A counterfactually used register will still be used by one of my differentiated copies, and ISTM that these alternate differentiated minds are essential to my consciousness, and that removing the counterfactually-used register in this case may well prevent my consciousness. To sum up, a counterfactually-used register is being physically used if many-worlds is accepted, so therefore the 323 principle isn't applicable.
