Re Taxing temples: Makes sense to have this as an option for realms, if they want to tax temples. However, I worry about what this will do to temple funding. This will be a serious drain on temples, requiring them to be visited much more frequently to keep the treasury stocked so they don't fall apart.
Re Taxing SSs: Wut? This makes no sense. The reason the treasury cap was put in place for SSs is because they are not taxed.
