As far as prepping:
Problem with large SHTF, TEOTWAWKI scenarios is the Golden Horde. You'll have hundreds or thousands at your farm wanting, stealing, & killing for food.
I made my mind up I couldn't lethally harm starving kids that would show up and eat all of our food thus long term survival planning isn't practical for me.
The ruthless gangs that would form after SHTF out looting and plundering would be my demise.
Since the medical estabishment would also cease to exist along with public health water and sewer services, epidemics would spread like wildfire, which might get you first.
As far as gangs although things have changed a lot since consider the fall of the western roman empire and the protection racket that was feudalism, i.e you gave your land to the lord in exchange for his protection. Likely would happen again as ad hoc versions of governments lead by strongpersons took over.
