I don't know much about "Gundam," and to be honest, I don't understand the contents of the current "Witch of Mercury" series at all.
However, I could see that this animation depicts a conflict between earthlings vs. space people.
The story of this conflict reminded me of "Bye-bye Jupita" by the late Sakyo Komatsu.
Unlike "The Witches of Mercury," "Bye-bye Jupiter" is set against the backdrop of space people (or rather, "engineers working in space") who are trying to leave the solar system further and further away from the Earth.
"Earth's people fear that the space people are abandoning them."
It is the concept of the book.
-----
The space people try to use their power (technological power) to expand into space as they please, ignoring the Earth, but the people of Earth interfere with them with laws and systems.
This is because the people of the Earth have the idea that 'the earth belongs to the earth, including the solar system.'
The same things are frequently observed, like the following.
(1) Europe, which never allowed the independence of the New Continent (North America) (200 years ago)
(2) Employee invention provision in the Patent Law (Article 35(1) of the Patent Law)
(3) Parents who do not allow their children to attend college in the city or to study abroad.

I have always resented individuals and corporations who have been stingy with everything I do.
So, at least, I try to remember that I should not just be stingy with what others do.
However, it is not enough, and what is the most important, I think,
"Prepared to be cut off and abandoned anywhere, anytime, and not resent it."
In my case, "karma and retribution" are perfectly applicable, so I think I am quite prepared to be "cut off and abandoned."
On the other hand, those who want to do something must be prepared to shake off, kick, and trample over people and things that hinder them and move forward.
