Statement 2 is more plausible than you think. Given the stated sizes of the spheres, it’s highly unlikely that they exist solely as prostitute storage units. I’d suggest that they’re aerial habitats, and prostitutes are just one of their many exports to the surface. They also offer really awesome bungee rides.
Alternatively, they could be organism production facilities, and the prostitutes are produced on site upon being ordered. They also offer pet velociraptors and colorful ponies.
The concept of “should” is not one the universe recognizes; it exists only in the human mind. So yes, his ideas do determine what should be.
Besides, “life sucks, let’s fix it” and “God doesn’t exist, let’s build one” are far more productive viewpoints than “life sucks, deal with it” and “God doesn’t exist, how terrible”, even if they never amount to as much as they hope to. The idea that they “will only cause harm” is incredibly nebulous, and sounds more like an excuse to accept the status quo than a valid argument.
