This system of morality is cute when we compare a rich man and a pauper. It falls on its face when we compare a violent heathen and someone who tried to live well. It's lazy nihilism by another name, an absolution of moral agency, albeit with compelling dressing.
Our "moral agency" is no different from that of a dog's, it's just the evolved game theory outcome of many millions of years living as social animals. It's an intuition about when to cooperate and when to compete.
As social animals we have devolved into violent heathens regularly throughout history if you think those violent tendencies isn't hardwired into your own DNA you're kidding yourself. When a technology is invented all of it's negative externalities and misuses are invented as well, and if said technology is used for violent heathenry, it's inventors are complicit.
And yes, I'm lazy, that's a win condition, why wouldn't I be? What were all those labour saving devices for if not so we can be lazy? Climate change is humanity's biggest threat. It is entirely the fault of people doing things, they're making a huge mess. Just chill out.
