My initial ideas (e.g. cases where time are important) are pretty well captured by other comments, but in reviewing my thoughts I noticed some assumptions I was making, which might themselves qualify as additional requirements to eradicate trade:
A) I assumed that the skill-download feature includes knowledge downloading and no task requires more ‘knowledge+skills in active use at a time’ than the human brain can feasibly handle. If this is violated, specialization is still somewhat valuable despite free and presumably-unrestricted knowledge-sharing. If you add immortality, reliable perpetual staving-off of the end of the universe, & a lack of boredom I doubt this assumption would still be required, but I haven’t thought through it enough to be certain of that.
B) I assumed that fundamental computational/cognitive ability is not an issue (i.e. working memory capacity limits, which can be helped by group-problem-solving even with equalized IQ), either because ‘build AI to solve problem’ is among the downloadable skills or because the problems themselves do not require it. If this is violated, then cognitive enhancements will also be required to truly eradicate the inequalities fueling trade.
C) I assumed that terminal goals don’t inherently involve interpersonal conflict (the subset of conflict-space that requires multiple involved agents in order to exist). If this is violated (i.e. everyone has a passionate love for gladiator fighting) then such conflicts would likely qualify as trades (since you can’t experience them on your own, and thus are both gaining the experience from another and granting it to them). Plus, depending on the broadness of the conflict-types desired, trade itself may be invented as an independent cultural concept, purely for entertainment purposes.
