Even if you imagine a hypothetical national co-op to consolidate multiple cities, customers would still then have inconvenience of Country_X_coop and Country-Y_coop. I strongly suspect city level coops would consolidate easily and naturally once they would develop a strong base in their respective cities. Besides, consolidation isn't the only way this might go: a lot of the software work can easily be ported from one city to another - if for example the current NY coop catches on, I think it would be quite easy to spin off a Boston coop for example. Regarding international travel you should ask how often does that need actually occur. Quite few people travel internationally so much that having a couple of different apps on their phone is a real inconvenience.
