The side effects they’re finding are that it unexpectedly prevents Alzheimer’s symptoms and other neurodegenerative issues, influences the brain to want to drink less alcohol and smoke/vape/chew less nicotine, and helps with chronic pain.

The point, though, is that it makes metabolic changes by having people eat less. Pointing out problems with drugs that increase resting metabolic rate (so that they burn more calories without exercising) or decrease absorption of macronutrients in digestion (so that they take in fewer calories from the same food) doesn’t really inform how we look at these behavior-altering and desire-altering drugs. They’re losing weight by eating less, not by interrupting the relationship between eating and net caloric intake.

It makes them eat less which they even can ignore

What are you talking about? If they’re eating less, then it’s working at changing the behavior. What is there to “ignore” at that point?

You’d never get Kessler syndrome at Starlink altitudes.

Starlink satellites orbit at around 550km, and get dragged by the little bit of atmosphere that is at that altitude. Each collision might make more debris, but the conservation of momentum means that any debris that gets kicked to a lower orbit will probably burn up on the atmosphere while any debris that gets kicked to a higher altitude will be smaller mass and therefore cause less damage on the next collision after that.

Collisions can still happen, but the runaway conditions where debris begets debris won’t happen at those orbital velocities and altitude.

Because the overhead of weighing passengers and their luggage for every flight would completely wreck the logistics and make it both unpleasant to fly and unprofitable to operate.

Obesity has long term complications, too. And we know them to be bad.

No, the drug changes the habits. It quiets down food noise in the brain (not always thinking about food), and shifts people’s tastes/preferences in food. It doesn’t change how the body processes food, it changes how the brain wants food. So the habits change pretty quickly.
