Well, unless you're hunting NPCs (which is pretty boring), bounty hunting is not a reliable source of income.

But you can run a small or even solo pirate operation, preying on lone travelers. Or run goods to dangerous markets in stealth transport ships. Or in a much much larger, much more expensive jump transport ship (just don't get ambushed!). Or start a manufacturing operation. Or for the truly hardcore (and really best done in small groups) go make a living in a wormhole for a month or two.

There are nearly countless things you can do solo or with a small group. The easiest way is to be part of a large alliance and have "safe" space to operate from - this does not, generally, mean you have to follow orders. Or you can operate in neutral space - everyone you see is a potential friend or enemy (more likely enemy). Or you can go deep into enemy space and play cat and mouse with an entire alliance for hours or days.

So... yes, I guess?
