I agree. Also, our planet is limited. Thinking that we can increase production infinitely ( good economist point of view), is just physically impossible

0.9 + 0.09 + 0.009 + 0.0009 +...

Seems physically possible to me.

With 10^27 g of Earth (without utilizing extra-planetary resources) each of which can be broken down into around 10^23 mol/g of stuff (without significantly altering the material composition) your infinite string of numbers will only be about 50 digits long.

That's rather "infinitesimally", not "infinitely".

We're talking about infinite time, not infinite space.
