Kinda fucked up tbh

Let's make some artificial rule like you need to be not on earth for 48 hours to be not on earth or something ...
Can be at rest in your own reference frame without falling to earth?

Hmm, I think this logic kinda fails because if astronauts are "not on earth", then neither are air travelers.
Astronauts orbiting earth are just couple kilometers higher altitude
We already have a definition for this, the Karman line.

Unless you define "on earth" to be "below the Kármán line. The Earth's atmosphere is probably to be considered part of the planet, else gas planet like Jupiter get difficult to talk about consistently. Atmospheres don't have a proper "cutoff", they just get thinner and thinner until they gradually become insignificant, so some cutoff is going to have to be arbitrarily defined to make the distinction useful.

I mean 30,000 feet is 9km. The Kármán line is 100km. The ISS is at an average altitude of 400km.
It's a bit like saying people in planes don't count as flying because then people on trampolines should count.

Karman line could be a good limit sure, but I think the orbit still kinda makes sense to include "on the planet".
Say for example if the apartheid baby gets his Mars colony thing going, from Earth's perspective it wouldn't make much difference if a person is standing on Mars surface or on the orbit - we could say that the person is on Mars.

When I jump, I am not in earth.

The Moon is not on Earth.

No, you're over Earth.

They would be in Mars orbit, but not planetside. "At Mars" might be a middle ground designator.

Are you saying that people jumping ARE on earth? Because I disagree.

Can I define my reference frame any way I want? Because if so, yes. And also no

The moon and earth are "on" a shared center of gravity. It just so happens to be inside to earth, so meh, we win.

Space is a priority so we can ignore climate change. Rockets put our many many plane flights worth of pollution, elon musk has done over 30,000 of them (mostly for StarLink). Quite a few ended up just dumping raw pollution and parts into the ocean.
No price is paid but by the environment.

Pssh, those are only the humans we know of.

Holy shit.
I've never been alive in a time when every human has been on Earth. That's crazy to think about...

Rockets are launched so infrequently that their effect is negligible compared to other sources of pollution. They're definitely still a problem (debris falling on populated areas is a concern), but the aviation industry burns a rocket launch worth of fuel a few times per minute.

Well, technically speaking, we all are in space.

From your own reference frame, wouldn't earth be falling to you? Because then this'd apply to everyone, always.
