When the government runs deficits, tax cuts are neutral against inflation but good overall because the money would be spent anyway, but at least it won't be misallocated by the government and their cronies. So, if they were simply counting the taxes they will stop collecting and misallocating as "spending", that'd be OK.

The problem is that's not what's going to happen because they will not just stop collecting $13 B, but a much smaller amount. They will keep issuing debt and having the BoJ buy it with freshly printed yens which is the real problem.
