It seems that you're implying that humans shouldn't interfere with any celestial bodies because of the inherent value of their pristine existence.

There's so many engineering and scientific advancements needed to make space-based sustainable colonies using materials sourced solely from Earth that your position would delay any colonization of space past a few great filters.

I was enjoying your takes on preserving Mars, but saying that humanity should only be allowed to change Earth is nihilistic in the extreme.
