Sorry we can't move (within the next decade or two) to Monero's absolute anonymity. Sorry. We need a more pragmatic approach for Stage #5 of the global economic collapse because the State will still be strong in Asia and destructive in the West. I propose anonymity that is compatible with taxation, because Asia will have strong States not total collapse.
I don't see the use of anonymity if you allow for taxation. And in fact, you can never prove that you declared everything.
Apparently you did not understand technically what
I proposed upthread. We can in theory anonymously (in zero knowledge proofs) prove the tax reporting period totals on our inputs and outputs from transactions we've participated in (but apparently not with Monero's current technology).
You can prove that everything related to these addresses you own, is declared. But you can never prove that you DON'T own the keys to other addresses. What if you owned them, and lost them ? How can you prove you have forgotten something ?
The point of proving what you declare is that if the law does a dragnet and finds you were lying (or uses the NSA to unmask the anonymity), then you have a problem.
But if you declared everything, you have no risk of a legal problem (assuming the law is unequivocal and adhered to).
This is not much different than cash businesses situation we had.
The alternative (as we discussed in detail upthread) is complete submission to absolute top-down totalitarianism or warlord chaos with no blockchain privacy, or alternatively illegality with Monero.
