Yes, but don’t you see how then you run into the question I’m asking. Which is, we know there is also usually dina d’malchusa for other stuff besides taxes, and so then that must be for a different reason. But the ?? never explains why that different reason doesn’t apply to taxes. And never even explicates that there are two different theories of dina d’malchusah, and nobody else I am aware of says such a thing either.
And taxes back then were also for public services. That is, for the king’s protection, and for his public works (roads, aqueducts, etc). I don’t see any difference between the taxes then and the taxes now except in the means of collection, and the reason we switched from a tax farming system to a direct taxing system is that now we have the ability to confirm your income through third party reporting.
