Orrrrr, maybe we take our kids out into the world and expose them to things, maybe give that immune system a nudge, little test drive right? Maybe we model what it means to be a productive, useful member of society...or in your plan we hole up and teach them the world doesn't want to hear from them, they're not important...shut up and fall in line minion. When my daughter was 2 months old, we flew back home to let the family meet her, we chose a seat all the way in the last row, and made nice with our neighbors, who were all very accommodating. As soon as they pressurized the cabin, her ears hurt, she cried, my wife nursed her and all was better. We apologized profusely, and actively did something to remedy the situation.
I'm sorry you lost your parents so young, that truly sucks, but just because you lived one way, should we expect society to have to go through exactly the same thing?
