The article doesn’t consider that in a world with a million satellites in orbit, launching space-based telescopes—including into deep space—becomes an order of magnitude cheaper.

Does it? My understanding was that it’s less helpful for anything which isn’t in low-earth orbit because the commercial launch engineers are optimizing for the lucrative satellite business, not larger and higher payloads.

Google says that James Webb telescope cost a total of $10bn. That's not a lot of money in the grand scheme of things. Private citizens could afford to put similar things into space if they chose to. We don't need them to be cheaper.

Here's a visual to consider the implications of things you can do with actually one million satellites of the kind of size scale being discussed:
