I have never heard of 'early throat erosion' being an issue with adjustable gas blocks either.
While the venturi effect in theory would place more pressure on the adjustable gas block one would hope the manufacturers have considered this and use the right metallurgy and components. If the block lasts as long as the barrel then that's good enough for me.
Seems to me there's little difference in an adjustable key or block; including disadvantages.
