Letting the oil circulate before putting load on the engine. Only needs an extra 10-15 seconds, or the time it takes me to scrape during the winter months. No time needed if it was recently running.
Theoretically, yes. Functionally, no. When you go to pay for something with your infinite bills, would you rather pay with N number of 100 dollar bills or get your wheelbarrow to pay with 100N one dollar bills?

Salary? No. Stipend, yes. Give me enough to comfortably live on and pursue interests and hobbies with no requirement for work. That’s the closest money would get to making me happy.
