If the government wants a tax to be paid they need to make it simple and unconditional. If there are loopholes or ways to legally avoid it, they will be discovered and people will take advantage of them.
In a good and just society there is a large overlap between them, and in others there is less overlap.
But it's impossible to build a legal system where there is a 100% overlap, and it would most likely be a broken society in other ways.
I totally agree with your second paragraph, that the government needs to remove loopholes and other ways for people to weasel out of contributing to society. But there will always be some corruption and a lot of money to be earned by only taking from our shared resources and never contributing back.
If you’re going to argue the majority, then I’ll remind you that the majority had no problem with slavary either not too long ago in Western nations.
If you’re goning to argue democratic values, then I’ll remind you that many brutal dictators also rose to power by the same values.
So put another way , by which definition of morality are we drawing this diagram?
