I don't know if this is the right forum for this, but here goes nothing...

You get possibly (if it even goes off well) a fraction of a difference in latecy (there is a limit...)......if....for what cost?

30ms latency anywhere on Earth is comparable to traditional cable internet, which is impressive for satellite communication. Ever listen to two people trying to talk via satellite and there's a 1-2 second delay? The limit is the speed of light traveling over distances. Starlink satellites solve this by having orbits very close to the earth - it's a big difference compared to latency in the 250-300ms range.

Rediculous expense

I don't know about you, but cable internet already costs about $80/month in my area and the price keeps going up (along with faster speeds as they upgrade the cable network). Starlink is comparable price without having to run wire - so you could get service out on the farm, or anywhere remote.

Space Garbage; Increased Complexity of collisions and possible fallout effects;

This is true, but I think it has been exaggerated a bit. Space, even at Low Earth Orbit, is pretty big. All of the objects large enough to be a problem are tracked and have a known trajectory. Starlink satellites are designed to deorbit automatically after about 5 years and break up during re-entry, so if the project does go out of business the problem of space junk will solve itself.

proprietary system with no way to debug it yourself;

I haven't looked into this. Are you talking about the dish/antenna? I suppose it has to be proprietary or else people would be able to use the service without paying. A system this expensive couldn't be free.

Monopolistic end goal;

I don't see how it's monopolistic. If anything it's the opposite, since it is offering an alternative to the cable companies who have a strangle hold on the ISP business with the help of government stifling competition.

Possible human rights violations on the global scale;

I agree this could be a problem with tracking, but no more of a risk than a regular connection to the internet. Most people carry a sophisticated tracking device in their pocket already.

A new technocratic boundary that physically separated the haves from the have nots through a subscription model;

I'm not aware of any ISP that doesn't use a subscription model. I don't see what the objection is here. Perhaps you could elaborate on this one.

How about when someone else decides to compete.....?

I don't see a problem with this. Just like we had Sirrius and XM satellite radio competing. Competition is a good thing.
