It's not even ASIC hostile. You seem to be under the impression that ASICs are somehow incompatible or inefficient with Scrypt.
It seems that you haven't read my post before commenting it. I'm talking only about ideology, not technic details. It's obvious that it's impossible to develop a real ASIC-proof algo, and this guy said more than enough about this:
https://en.wikipedia.org/wiki/Alan_TuringScrypt coins are asic-hostile systems due to ideological reasons. That's all that we can say.
The more general version of "asic-hostile" is minimizing barrier to entry in a market.
Minimizing the barrier to entry is a very good idea, because it increases competition. If competition is important for the safety of the network, using a problem with the lowest barrier to entry is the best choice.
Low barrier to entry can be translated to "no need to invest in asics or any specialized equipment".
