Tradeoffs, sure. but trading off literally all of your sovereignty and ability to support yourself is a pretty steep one. It's a good incentive to be 10000% sure you're committing to the right person (and that he doesn't get kidnapped, or develop a gambling problem, or wrongfully arrested, etc. etc.).

The same way everyone should learn basic self-defense because you can't always count on someone else protecting you - everyone should consider what kind of valuable work they'd be able to do if they needed to.
