As we all know, studies on separated identical twins show that happens every single time, with no exceptions.
points of trade
Information exchange.
Even if you have teleports, you don’t know where things are. Distribution of resources still matters even with ‘equivalent desires’ - if a car needs iron and platinum and other things and I have iron and you have platinum...neither of us has a car. (If the teleports have zero energy cost, or involve perpetual motion machines the case for ‘why trade’ just changed dramatically.)
Sharing information easily doesn’t mean reworking information, or combining info is all that easy. Joining two fields, working out the implications of information (see Hawking radiation)...
Even if ‘one brain is the same as another’ - which is ridiculous. It’s not even just about brains—then two heads can still be better than one. Whether that’s together, or apart.
Seriously, the reason these factors aren’t all the case might be worth some consideration. That’s a lot of ifs. (We don’t have the transporters or robot armies. Or do we?)
