My argument is mostly, that if you don't have enough of an audience to remain open, and there is generally enough of an audience in the area of the restaurant, than it's upon you, not the (potential) customers to adapt.
Sure; I'm calling that unreasonable, but not incorrect. The market determines what is profitable, not what is good. Ultimately if you want something good to persist, you must also ensure it is profitable (or find ways around the market -- subsidies), but it not the case that profitable things are inherently good, and it is not the case that things are inherently not good because they not profitable.
So I say it is unreasonable to hold onto something good in the face of lack of profitability, unwilling to change, but it does not say anything about whether they it was produced well for the audience they intended to serve (it is simply the case that their intended audience either does not exist, or does not exist in sufficient numbers to be profitable -- or it was poorly produced for the intended audience).
