Lol a few careless moments with a woman would end his lifestyle in a hurry. When the judge orders 20% child support they'll impute the income at whatever you can make slaving away at a desk, not what you make in a relatively carefree life with fish and wildlife. In California that would be $20k+ (post-tax), so basically almost all the post-tax income of a low level fish and wildlife worker, assuming you're even lucky enough to get the full-time job.

I lived a somewhat similar life basically enjoying living outdoors and odd jobs and travelling and volunteering until I had a kid; would not recommend consorting with women unless you want to be on the hook to pay rent and chained to a desk for 18 years.
