Yeah, because no one else does that, certainly not Ariane that get so
small and insignificant (as you said) subsidies - barely ten times bigger.
First of all, would you come with numbers about the subsides?
But let me tell now something about SpaceX and especially the Falcon 9. The cost of a Falcon 9 cost around 56 million dollars, but does this also including a insurance if the Falcon 9 fails somewhere in flight what cause a lost of the spacecraft? And what would be the real price of a Falcon 9 if everything, including R&D would be totally 100% private funded?
There is a risk in asking and using government funds for a start, that risk is that it would start great and cheap, but when the government says like "Ho, we go stop funding you" then the product would likely rise in its price. Sometimes just a little, but sometimes gigantic.
Also a weak point in that is that you company become really a big risk economic if there are bad times and the government need to cut. So its economic already a risk. But on the other side, economic goes sometimes just about taking a risk.
But back to the core of this discussion. Why I should launch me GTO satellite on a brand new Falcon 9 who still got a few launch history? I can go to the Chinese to launch the satellite for a lower price. Or to Russia and ask to launch it via the Proton M who got a long launch history and got a high success rate.
What I mean basically is that SpaceX is maybe in its form now the cheapest provider of rocket launches in the US (and maybe even of the rest in the western part), but not the cheapest, there are other rockets who are less expensive then the Falcon 9, got a longer launch history, more successes and can put something into GTO with even a lower price per kilogram.
And no, go not kick on with the argument that the Falcon 9 become much cheaper because reusability. I don't see that the Falcon 9 would really become reusability now or soon. The first real test of it did failed, what was expected. Next try of testing the Falcon 9 with at least a 'soft' landing on the water would be with the CRS-3 mission.
Grasshopper is just a small test rocket for reusability, only to test just some hardware for the landing. But for the rest the Grasshopper is just miles and miles away from a real first stage of the Falcon 9. Do you even think that landing legs on the Grasshopper would even survive a supersonic flight? No.
And who would pay the R&D of it? I never did read something about the financing of those R&D projects of SpaceX.
And even when there got the landing legs and have a reusable first stage of the Falcon 9, then still we forget something. How much fuel it would need to return to the landing place on land? And how much mass it would cost a reusable Falcon 9?
So to hold it short: Arianespace would stay for at least some years, because SpaceX is still miles away to become a real competition for them. However in the long term, it would be crucial to work together with the Russians.
