I suppose nation-states aren't the only ones who'd like information on US military bases/infrastructure/"nationalsecurityinterests", but I honestly think it's irrelevant. If we were discussing serious imaging systems then sure, but it's pretty clear that a webcam isn't going to give anyone any meaningful information.

The point is that you don't hand out the license trivially. Yes, spacex is just discussing this in the context of a glorified webcam, but webcasts aren't their only business. Such a license needs to consider the whole business. Now the NOAA perhaps should consider a type of limited license, but they can't assume the only imagery technology spacex is interested in is webcams.

That's a list of nations capable of launching stuff on their own. Compare with this list:

Non-space-capable countries do routinely put their payload on the rockets of countries with launch capability (though I guess then it can't be an obvious spy satellite).
