I just described how terrestrial material is compared and detected with hypothetical extraterrestrial material.

If extraterrestrial material has the same isotopic composition as Earth's, then you detect nothing!

If terrestrial material has abnormal isotopic composition than "Earth's average", you are fooled!

We've sent first probes into space in the 1950's, I don't see Elon Musk, Jeff Bezos or other capable people pursuing your scenario - distance will always be the main factor and a single planet resource will never cope with it (I know, it sucks)

So if Elon Musk hasn't suggested it then it has to be impossible? The whole point of this is that one planet doesn't have to support such an enterprise. In fact that would be close to impossible but there are plenty of resources already in space, asteroids, Jupiter's Trojan asteroids, Kuiper belt objects, and those good old oort cloud objects not to mention such objects in interstellar space.

Phi, you should be knowledgeable enough to know there is just one stable isotope of Aluminum with 13 protons and 14 protons neutrons

Obvious misspell..

This is an interesting short video about colonizing the galaxy via star motion. I still think that planets are unnecessary to the point that planets will be ignored and actively avoided. This gives a interesting slant.
