We can anticipate some businesses would benefit from having low-cost access to microgravity environments - right now you carefully select your experiments, because it's extremely costly, but, if it weren't, you wouldn't need to.
While satellite/probe/crewed-craft building has an extensive industrial chain with multiple bottlenecks that would hold it back if launch costs plumeted, there are others that have few and that would be enabled.
We'd probably need a lot of barriers so that people don't launch cubesats for $100 in volumes that make LEO dangerous.
Nobody cares about satellites themselves. What they care about is using them for something useful. Communication and imaging. At some point, both markets will become saturated.
I don't know what level of demand there is for them, but it's entirely conceivable that it will be long-term limited by something other than launch costs.
If you lower the dollar cost of going to the dentist by 10x, you're not going to see people going to the dentist 10 times more often.
