I think this is usually a problem which is more easily solved by better funding tax authorities and installing better oversight rather than by making it easier for people to not pay tax.

I think most people's tax affairs are pretty clear-cut to assess (e.g. if you are an individual earning an income or run a small business). People who structure their tax affairs in convoluted ways where it becomes non-trivial to work out what the correct amount of tax they should be paying is (or even a question which can't really be answered until you are in caught) generally have a lot of money or are trying something stupid (e.g. trying to pay yourself your salary as a loan through an offshore company where the tax authority are obviously going to think this is illegal, see https://taxpolicy.org.uk/2024/01/18/barrowman_fraud).
