1....Yep just a theory, but one that explains the Population Bottleneck at that time. 2.... 'Modern Food Preservation' is not a positive but a negative if highly automated, energy intensive, complex, "just-in-time" food supply chains are disrupted due to massive grid & transportation failures due to a Yellowstone VEI-8. 3...."The 1996 farm bill replaced the physical FSCR with the Bill Emerson Humanitarian Trust, shifting from physical stockpiles to a cash-based system managed by the U.S. Department of Agriculture and used by the U.S. Agency for International Development (USAID) for food assistance." 4....Volcanic Ash becomes a conductor when damp...so a rain/snow & even fog/mist will accomplish that. Also damp volcanic ash tends to be very corrosive. It quickly air filters & is highly destructive to machinery. Trains, Airplanes, Vehicles are inoperable in an ash environment. The largest eruption in the last century was only a VEI-6 in 1912. The VEI-7 in the 1800s was far worse in human suffering/deaths & a VEI-8 would be nothing less than catastrophic. You seriously are underestimating what a Yellowstone VEI-8 would do not only to the CONUS, but also the Northern Hemisphere. Basically one of the absolute worst scenarios that could happen to civilization. Human history would basically be "Before" & "After" the event. FWIW...."Supervolcano" is a decent movie based on fact about what one would look like. Personally I think the human effects were watered down for public consumption.
