I think I read something different from what you really meant, because that's not true by the very definition of resource.
I meant items like food, water, appliances, etc. Otherwise, yes, we're down to a semantic quibble over what "resource" means, which I don't think is very helpful.
I don't think it's silly, in the sense that the future will see a lessening of national borders and national exploitation of resources.
Certainly it is. If there are not enough resources to keep seven billion people at a reasonable standard of living, what possible incentive is there to share?
There are already strong immigration/emigration fluxes, and the future is probably going to bring about an increase in population
Let me just leave this here.
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
To any future monthly posters of SQ threads, please remember to add the "stupid_questions" tag.
