You're so close to having empathy for all people! Just keep going: What if nobody had to justify their existence?
Edit: Downvoters, try a little harder. Engage your emotional core. Really work those empathy centers. Think about it: If nobody had to justify their existence, and people just allowed each other to exist, then we wouldn't have to weigh whether sex workers are more deserving of rights than computer scientists. We could allow both; we could allow everybody.
Since nobody had the temerity, I'll answer. If nobody had to justify their existence, then our society would not need systems which destroy people. It's that simple, and the folks using downvotes instead of words should confront their biases.
