I am sorry, I used 'marginal' in the economic sense. My point is that there isn't a huge barrier to entry on working titanium like there is (so far) in producing carbon fiber. Yes, titanium is much more labor intensive but you can charge a higher price for it so it works out okay.
... and your point is? You are essentially describing a market that has no barriers to entry. A market with no barriers to entry is not a market that will "shake out" as this thread's thesis requires. Yes, some companies will go out of business, but they most likely will be replaced by new manufacturers in the short term.
Now, the new so-called "trade" policies might actually create those barriers to entry. So we will have to see.
