It's not about buying time though, it's about what you do with the bought time. I see a lot of people using these expensive services and then wasting the extra time - or worse, filling time while they wait for the completion.

Time is time. If one values doing nothing more than doing house chores, then they are buying time by paying a cleaner.

It is about spending your time doing what you want (including doing nothing if that's your thing), and outsource the things that you don't want to do.
