It's actually not a science/technology problem. The problem is human nature, and that's not solvable with technology. If it was, then everything would be rather simple...
I think it's a problem of politics, just like you say, it's not about technology, of course. But it's an issue at the cross section of science and politics.
Maybe you can also see why the young climate activists use banners with "system change, not climate change": They don't believe, either, that our current sociologial systems are capable of solving this, the "system" needs to change.
Yes, I agree. The question is what the system need to change into?
I'm not an expert, but it seems that all known political and/or economic systems fail in the face of greed and selfishness. Or maybe greed is the effect of a failed political system, either or all known systems are a failure from my perspective.
I think capitalism balanced by laws has worked best so far, but you seem to need so many laws that it creates loopholes. I.e blacklists doesn't work that well, especially not a complex blacklist. (And I'd even suggest that the blacklist has been trojaned by lobbyists and other agendas.)
