I think you're interpreting something into my comments I didn't say.
My point is that every product was hilariously under delivered, not that the product itself is unusable.
Let's address the products you're citing:
The Tesla model s was marketed heavily on price and the full self driving.
There were essentially no electric cars in the 100k price range the Tesla cost, so comparing the cars at the time the car was announced with when the car actually was delivered, 5 yrs later is extremely questionable.
But without Musk's hype, we probably wouldn't have the rivian etc, as they were all riding his hype wave. But we'd still have electric cars. Just less then we've got right now.
Now SpaceX's.
It got billions of taxpayers money, there can be no second company because nobody else can get such funding.
In the nineties pretty much everything was delivered by NASA. It just threw in the towel for price reasons, so Musk came along and promised a lunar base & manned missions to mars, netting him all contacts.
So yes, now we have SpaceX. The only player that can deliver things to orbit, because Russia is too poor, European nations somehow don't want to spend money on it and China is mostly interested for military applications, so they're not publishing what they're actually delivering to orbit. They're definitely shipping things however, you occasionally get leaked videos from failed launches that spread toxic fumes close to population centers and similar fuckups.
What you're using as an argument is really an inevitability.
Starlink is another highly exaggerated product, which is still decent value if you need/want an Internet connection in an area that doesnt have usable cable connections. It's not the cheapest, nor the most expensive. It's in the middle. It's a solid choice (and so are the Tesla), it just didn't have quite as much impact as people attribute to it.
I'm not even bashing Musk. What I said from the start is that his contributions are exaggerated.
