Or you exchange that money for other people to do those chores. Home cleaning services, landscapers, electricians, plumbers, car mechanics and drivers (including Uber/Lyft/taxi), cooks or restaurant/takeout food (often plus a third party to deliver same), nannies, dog walkers, and so on. Specialization is the name of the game. I can do some of these things myself, but I can also earn enough in one hour to pay for multiple hours of other people's time and expertise (and amortized equipment). That's a pretty big win compared to a 14th-century tradesperson, or even most nobles.
