You could say the same thing about any military hardware during a peace-time economy. It’s not a matter if it exists, it’s a matter if the relevant knowledge exists in domestic/friendly industrial base. The U.S. is making more satellites than the rest of the world combined right now.
It's also whether it matters if you have people available to replace the things. Any conflict that gets to the point of taking out satellites will almost certainly trigger Kessler syndrome, at which point whether you can launch any more satellites becomes moot.
