Yes, I would spin move hit a stranger every day for a year to decrease the tax burden by one percent at each level. On the one hand, of course I would just because I fully believe that the overall societal good done by getting the money out of the government's hands into the hands of the people vastly outweighs the negative of having 365 people hit by me on a random day. We're talking about billions of dollars that people get to decide what to do with using their best judgment instead of pissing it away on wasteful or unsustainable programs probably in the military, HHS, or Social Security. Just a 1% decrease across the board would be amazing for the well being of the nation.
On the other hand, it's valuable to analyze the cost of the spin-move. So what are we really talking about here with regard to the hit? Well, we're talking about basically assault, effectual or ineffectual, and with that comes a large degree of personal risk. Even though I'm confident in my ability not to seriously hurt anyone doing some silly karate move on them, a lot could still go wrong. If I get to choose the location and time and the stranger, then I'm even confident that I could go the whole year without winding up in prison or with a hefty fine. If someone else is choosing, well then I'm just biting the bullet and doing some time and making America great again. You're welcome. But if I can choose, I'd spend hours and hours each day scouting locations and potential candidates, trying to find people with senses of humor, people who kind of expect that they might get randomly attacked and wouldn't mind, people who probably wouldn't report the crime and/or run after me, and people who suck and deserve to be spin-move hit. I'm thinking college campuses would be a really great place to start. You think anyone would care if I busted a frat guy in the face with a weak twirling kick? I doubt it. And if that started to cause problems, well then I could always attack tax accountants and small business owners and then drop a flier that says, "I saved you money, here's why!" and then run away. They'd rub their shoulder and go, "Totally worth it. Thank you!"
A safe assumption.
