Can we try to keep (the deeply discretited) Hayek and the Chicago school, not to mention over-complicated philosophical jargon out of the argument? I would content that you should liberate yourself from the received wisdom of your philosophy course, and think for yourself.

The issue is simple: is protection of local industry justified in the face of globalization. Obliquely (not orthogonally), are local businesses adding social value, or is lowest cost the absolute and only barometer of utility. Only once we have answered these questions can we decide if Amazon is correct or not, and it is not going to help to cite a bunch of dead people, who, in my opinion, are very clearly responsible for the ills of our current society.

Far better, citing The Economist Style Guide, "think what you want to say, then say it as simply as possible".
