I'm sure it's possible to sit in isolation and create a livable startup. In my experience, though, the best things professionally, such as bizdev deals, finding people to work with or making large sales, come from personal connections. That is, people that you've actually met.

I love the outdoors and I love to code as well. This sounds super fun and I'm kind of jealous of that lifestyle, but I'm not sure if it's a sound business decision.
