vbo has posted several times on the transparently imperial nature of such bodies as the UN and the International Criminal Court.  The very idea of international law is ridiculous without the idea that there is some power capable of enforcing it, and the whole idea of enforcing legal judgements against sovereign entities is inherently imperial.

Actually you are right. It would be very naive to see it other way...It was obvious to me but I don't know about others.
But is it actually good? I don't think so.

what I am imagining is a complete collapse of the global order, where states truly feel free to, if not compelled to, fight it out amongst each other to build and protect their interests.

Do we have fewer wars as you are trying to implicit? I don't think so. As we look at the history those small neighbours conflicts usually did not escalated in full wars and had much less victims and destruction as opposed to "imperial" conquests or change of imperial powers. These were bloodiest and left half a world in ruins.

When I claimed to benefit from empire, I meant it at an incredibly basic level.  

As I live in one of the Empire "provinces" I enjoy those benefits (on a basic level) too. But I am afraid that the price for my "enjoyment" is going to come to my children and grandchildren...and I do not like it. Actually I hate it.

People want to learn English in this world, because it is the language of the Imperial power
 

Nap. People want to learn English language because it seems to be the easiest way to understand each other and to be informed. Actually people used to learn English in old days because of the good music, movies, books etc. that your nation used to produce. Not anymore. I haven't seen good American movie in ages and thanks to SBS TV here I am able to see some very good movies from all over the world. That gave me prospective to see what a shity American cinematography has become. Music? I am not that much in to it nowadays but I can't remember one single American song that will stay in my mind. As opposed to old days when simply everyone in the world loved that music of yours.

I am legally allowed to live in places where people want to learn English and are willing to pay me to do so.  All that has been nice for me.

If these are your reasons to support Empire I must say that they are very shallow. I can't remember time when you Americans were not able to travel around the world (except Eastern Europe and China and few more). Somehow I have a feeling that all tho you can travel around your Empire and more , you are not going to be welcomed in many places.
