Really? If I generate an offline copy of an article on my phone, wouldn't I want to have access to it on my iPad? Why wouldn't I want the truth to be in the cloud?
Because there's no point in burning your cloud storage, Apple bandwidth and prolong backup times when those articles can be easly re-downloaded from Instapapers servers on iPad.
Same result, without long backup times, Apple server bandwidth usage and your iCloud storage usage.
...when those articles can be easly re-downloaded from Instapapers servers...
My premise, in point #2, is that this actually isn't the case with respect to Instapaper's raison d'être. In fact, that's sort of the premise behind much of Marco's post too.
So really what would make everyone is a type of Selective_Sync, i.e. there are three file types.
those that are ephemeral and can be deleted.
those that are ephemeral but should only deleted if given permission
And those that need to be backed up.

That's kind-of the issue though, is it not? One of Instapaper's strength is that it provides for reading in a nicely formatted and offline way. You don't need a connection to go through your IP stack, unless iOS has decided to clean out everything.
His point is, if you back it up to iCloud, to get any use out of the backup, you need to be online. Therefore it's a waste, because in that scenario, you can just download it from Instapaper anyways.
