You misunderstand the issue. It’s a significant problem for some kinds of observations and largely irrelevant to others.
Satellites don’t include light sources and there’s nothing to illuminate them when in earth’s shadow. In order to interfere with light based astronomy they need to be outside of earths shadow and someone needs to be actively taking a picture of that chunk of sky. As these satellites orbit eye close to earth almost the entire sky is clear near solar midnight.
Major ground based telescopes can also add a shutter to block light detection for the fraction of a second a satellite would interfere. Basically at extreme magnification you’re looking at an ever smaller percentage of the sky which means the odds of a satellite, even one of millions, being in the shot for a given second is low. It’s still an issue, but being 99.X% as effective is good enough not to be a major concern.
Where it’s a concern is whole sky observation where you can’t easily add a shutter and losing a significant portion of the sky every night is a real problem.
“Sooo....the stars at night really are big and bright, deep in the heart of Texas?”
What an ingenious business idea.
sky will be constantly twinkling, will be weird
we'll have to switch to space telescopes above LEO

Only problem is they are toxic as they burn up and create a lot of pollution
