Bullshit.
If you want to play with simulations that clearly do not reflect real life, go ahead, but to me the Real World data is presently showing opening unis killed 10,000s people.
And it makes sense too. Eat out to help out you stayed in your local area. The time periods were short, often outside, and many of the people mixing were already exposed to each other.
Opening universities meant 100,000s of people moved around the country, met in big groups during induction, lots of mixing of new geographic regions. The time periods were long, often inside, and all the people mixing had never been exposed to each other.
