These posts make no sense. You don’t need withholding. You tell your employer and that’s it, the employer doesn’t withhold. The IRS doesn’t get involved at all.
You still need to pay taxes. If you owe a lot you may owe a penalty because you weren’t paying a little with every paycheck.
Back when interest rates were high on bank accounts, I never did withholding. It paid to keep your money in the bank earning interest and pay quarterly taxes to avoid the penalty. Years later I had an accountant show me that I shouldn’t even pay federal quarterly because the average money earned in the stock market was higher than the penalty for underpayment.
It’s a nice thought but they referenced land mines. The idea that an AI shooting a soldier could cause a conflict spiral could happen with a land mine. Not to mention humans make mistakes too. A human soldier could the same (and has). Automated sentry guns have already been around for over 10 years.
