>"Heavy" industry, pretty much by definition, means it's way cheaper to do it on Earth than in space
There are things that you just can't do on Earth because of gravity. And if price of putting things into orbit goes down it will open door to a lot of innovations in space manufacturing and within a decade it will have it's first "killer app". I can bet on it.
> no amount of rocket development will ever overcome those physics
This is simply not true. Your saying sounds like "Heavier than air flying machines are impossible". There's way more resources outside of our gravity well than inside of it and moving things from space to earth is cheaper than other way around. Yes, moving all heavy industry to space is complicated and very expensive, but it will be eventually done.
