And this is exactly the sort of comment that grandparent addressed with their post. More stuff in orbit doesn't necessarily lead to higher risk of a catastrophic kessler syndrome event, if it's low-earth orbit. The risk is not the same as geosynchronous where it can stay there forever. The satellites themselves (and even the debris if there is a collision) will decay on a very short-term basis (single-digit number of years). By making launch cost-per-kg cheaper, it is now plausible to put things in LEO instead of geo or other orbits. And doing that probably actually reduces the risk of a catastrophic event, even if there is more stuff. Possibly higher risk of a smaller event, sure, but that is true of anything that puts more stuff in space. That's a generic argument that we shouldn't be doing anything in space at all, which I think is not compelling.
