The easier and more "automatic" any tax is, the easier it is to hide, and the less people understand that they're paying it. And as they become less aware of what they're paying, it becomes easier to take more.
OP is acknowledging the inverse is also true, and that if "automatic" aspects of the system were removed, people would become much more aware of what taxes they are paying, which would lead to public support for reducing the amount.
