With Starlink - offering cheap and high-speed internet access to currently underserved places is absolutely good and important, maybe even critical for long-term success and stability of some regions. It's not clear that this is the best way to do that. Kessler syndrome, light pollution, potential upper-atmosphere effects (ozone depletion), should not just be waved away. It's just more externalities piling up. Rich countries should be subsidizing these underserved areas around the world so they can put in infrastructure - cell stations, fiber lines, etc. - rather than filling up the sky.
Most riches we experience in this modern life... depended utterly on the energy credits we spent by burning the eons-old reservoirs of solar energy, of dead plants and animals.
Honestly not sure it's a win. Maybe they had less, but they had not destroyed most trees, mammals and insects (which we have already), and all that for what? For a future where we will most likely have much, much less energy, and therefore where most our modern system... will collapse.
