"Space" is 100km. The moon at its closest is about 350,000km.

So the jump from the former to the latter is... significant.

Distance is usually the wrong measure in space. Something like delta-v will give you a much better scaling as once you manage to get something to orbit the rest is actually a lot closer than it would seem on the ground.

Not to say the effort somehow becomes peanuts, cheap, or easy... but the jump in delta-v needed to go from "100 km vertical ascent" to "hit the moon 350,000 km away" is more like a ~6-7x increase than a 3,500x one. If the moon were instead 700,000 km away the factor would still be ~6-7x.

		Wow even as a bit of a rocket nerd i'd never thought about it that way, that's pretty cool!

And you need a serious amount of money, effort and expertise to each 100km with a rocket.
