I got mugged

This is one of the reasons I have a concealed carry permit. Whenever I go down to Mexico (4-5 times per year) with my wife, I am always carrying because there is absolutely no law enforcement that you can count on. If you're going in to an unsafe area, you have to be able to protect yourself and anyone with you.
(the above statement is indicative of a constitutionally protected personal choice. I am a former military member who has had extensive firearms training. If you would decide to look into some measure of protection make sure you get the proper training so that you will not only have the means but also the wherewithal to protect yourself.)

BTW, you were absolutely right not to try and drunk fight that guy off of you. If all you lost was a hundred bucks and a black eye, chalk it up to learning a tough lesson and count your blessings.
