This is just unrealistic day dreaming. You can go be in a field picking produce for work - we have a shortage of these laborers. Most people don’t actually want to do that, they want a cushy office job that doesn’t wear down their body and that offers them the ability to increase their skill and value over time.
The software engineer who thinks they’d be happier working in a field is largely just a grass is always greener phenomenon. It turns out that for most people, they don’t like work whatever it is, because work is done not by choice but by necessity.
