I'm one that does and sees it as a future.
Long term the Earth would be a place of inhabitance and space the place where resources are extracted .
Long term; one asteroid tracked between Mars and Jupiter has minerals that are estimated in the $10 quadrillion range .(16 Psyche,)
Long range we will run out of easily extracted resources on this planet and will have no choice but to look elsewhere .
Not so long range is the fact that inside the inner solar system there are estimated to be 150 million asteroids with various degrees of potential resource exploitation.
The idea of getting equipment to the moon would be challenging if it meant assembly on Earth . Parts could be shipped direct to the moon or to a near earth or lunar orbit substation. (like NASA’s Lunar Gateway, a permanent orbital station)

Launch costs are going down since private space entered the picture. They will go down more in the future.
I get it . This will not happen in our lifetime . But it will happen nonetheless.
