The bunkers are imaginary protection from nuclear war.
The bunker-sealing-kits are imaginary bunker-spoilers.
If you wanted to weather a nuclear war for real you need a fully fledged underground habitat, one that is self sufficient in everything, a fully fledged biome that yields food, geothermal energy, resource gathering , artificial atmosphere generators, … It would need to support a population of about 100000 people. More like a giant space station. You have to plan for unforeseen complications. A nuclear war could ruin the surface in ways that we can't predict. That means you need to include the capacity to rebuild civilization underground. The means to expand the underground habitat until a level of economic power and technological sophistication is achieved that enables terra-forming the ruined surface so that it once again supports human live. It means committing to a scifi scenario where the next 10000 years, humanity might have to larp as mole-people. We could technically do this, but lets face it, we won't.
Most people think that a bunker only needs to be a underground hotel room that has enough provisions. Explaining why that's wrong is complicated. Some rich people might see a bunker as nothing more than the ability to live out the rest of their lives, once nuclear war has extinct humanity, so they get to have the last party.
So with all that in mind, it's easier to tell people that those left behind will ruin their bunker and therefor the only option to deal with a nuclear war, is not having the nuclear war in the first place and idk throwing the WW3 lobby into a vat of boiling acid or something.
