So the extent that those can be argued to have in principle have a technical fix, it could be quite interesting to research the necessary technology (advanced crypto, byzantine networking argument etc) that could address them. eg payee/payer blacklisting by a large group of miners and "committed transaction" proposal to address it. However even for that type of thing I think bitcoin-dev would probably rather focus eg on something that has reached the stage of having a BIP. Eg it might be better to discuss early stage or speculative ideas on bitcointalk.org technical thread. https://bitcointalk.org/index.php?board=6.0 taxation in particular there are examples where even the political sphere accepts significantly anonymous taxation. eg for europeans with certain types of investment in a swiss bank, the swiss bank sends however many million as a single payment across all users per european country to their passport home country (minus 25% cut for the swiss government). Perhaps such things could be possible for bitcoin. Again I think bitcoin talk would be a good place for such a discussion if that was the OP question indirectly.
