That's a different argument than volcanos being mobile, though. In comparison, a volcano's lava is like the lightning or rain of a thunderstorm. So at this point, it'd be comparing Primordus to magma, rather than a volcano, where I'd argue that comparing him to fire (or a wildfire, inferno, firestorm, etc) is equally accurate.
But the magma is the actual destructive agent, and we haven't yet seen Primordus, or any ED actually, directly destroy anything (with the branding being a possible exeption, but a case could be made for that being more transformation than destruction). Instead of directly destroying anything, Primordus has his destroyers for that. IMO it's more like Primordus is to destroyers as volcanos are to lava. In the same vein, other EDs are to their minions as storms are to rain/hail/sand/whatever else gets thrown about which directly or indirectly cause the destruction. Also, wildfires, infernos, firestorms etc. are not directly caused by volcanos, but are triggered by lava, hot ash or pyroclastic flows. I would argue that that is parallel to the fissures that appear when destroyers appear and the lava fountains made by destroyer crabs.
The point I'm trying to make is that whether the ultimate source of destruction is mobile or not is irrelevant. It suffices that the source has a means to cause destruction at a distance and there are some similarities between natural sources and EDs. Volcanos and Primordus have the means and similarities as well as do storms and the other EDs. The similarities do not have to be in one to one correspondence with every attribute of one having an equivalent in the other.
