the above solution is silly expensive.

Expensive doesn’t mean that somebody is greedy, it means that it takes a lot of effort from a lot of people - effort that could probably be spent more effectively.

Equating expensive with valuable, while very much in line with rules coming from Economics 101, is very questionable in real life in my experience.

If talking about costs bothers you, just think of it in terms of time efficiency. We have a limited number of humans and time available to clean up the planet. What's the most effective way to use them?

This isn't.
