Nothing's stopping you from doing those. Just because you can 3D print a sculpture doesn't mean you can't carve one out yourself. Just because you can buy premade food doesn't mean you can't try cooking. Just because you can get veggies that are harvested by machines on a farm doesn't mean you can't try growing them in your house. Nothing's stopping you from enjoying the original process when there are easier alternatives, but getting rid of easier alternatives does stop lots of people's enjoyment for being stuck in the original process.
