Because you can just have actual local people do it right there and then? The point of a robot is to not interact with other people, presumably they will be much more expensive than having someone come over for a few hours a week to clean - the whole appeal is there's no other human involved to coordinate or be nice to.
There's some benefits, but also massive, massive society destroying downsides. In retrospect, the downsides of social media like addiction, social isolation, and political misinformation, radicalization were hand waved away. We were told "THINK OF THE UPSIDE OF SOCIAL MEDIA, THINK OF THE CONNECTIONS" and now think of how isolated and depressed and addicted everyone is now. The exact same thing will happen with AI and VR.
I am generally not very fond of unions, but prevent wage theft is a very important function Unions have historically done very well. If there ever was an argument for unions, better contract enforcement would be it.
Think of all the poor unsuspecting stars! Have we not drained enough heat from our own already? When will plants learn to stop appropriating energy that isn't theirs to take?
Of course the Falcon can be compared to the SLS. Both are vehicles designed to take things into space for crying out loud!
The figures are easy to compare as well. Just include these factors in your comparison! Even if we don't know exactly what those factors are, we can make a ballpark estimate the total difference and add that as a percentage to spaceX's final figure.
The idea that things can't be compared because they are different is nonsense. When things are different is the only time comparisons are meaningful to make!
Because things in space do not scale linearly, and sending 10x smaller sats is not the same as 1x 10 times larger sat. Some missions require larger fairing/lifting capacities.
