>Given how bad people are with money, the number of people who can't pay their taxes would skyrocket if withholding is replaced with the scheme you are proposing.

If I was optimizing my actions based on what would create the most anti-tax sentiment, this would be a positive outcome, not a negative one. What's worse than a bill from the government? One you can't afford to pay and that causes you to take on debt.

To be clear I'm not optimizing my behavior on such a metric nor advocating for others to do so. I was talking about the purposed hypothetical of lawmakers who were making such an optimization and what sort of laws they would, in theory, be supporting.
