That's a particular case where you'd get other benefits (spending time with someone you like when the weather is nice), you know that's not always the case. And for the cost of half a day's transit work a software engineer probably only needs to work for an hour (and a professional's half day will probably take a layperson a whole day).
If you enjoy the activity it's a whole different story.
Including money!
I personally would much rather spend a sunny afternoon with my nephew transporting 2 tons of gravel and playing outside than sitting inside an office to earn the money to pay someone else to do it.
