These people are extremely naive. They are thinking after The Event, they'll emerge from the bunkers to magically functioning society and rebuild everything from scratch into anarcho-capitalist utopia without that pesky government. In reality, the landscape would likely be filled with neo-feudal warlords and gangs fighting for control, competing and looting everything in sight - without the interest to rebuild or maintain anything: same short-term interests they apply for natural resources with extra urgency of survival and competition. Without a functioning government and democracy civilization reverts to earlier tribe-like patterns of power, which don't allow for a collaborative society to exist in one place. All the former wealth and social connections they have wouldn't amount to much, the bunkers can't exist forever even if they have thousands of years in supplies. They'll be found and opened by other survivors to loot resources or just exploded to prevent competition. They don't expect the world treat them as part of zero-sum game they play with it. They taking the bet people will not change or respect earlier laws and customs. The author idea that preventing The Event is a more viable strategy is dismissed, because its obviously cheaper to bet on smaller projects and its contrary to egoistic drive. They're not concerned for the course of world history, they're concerned with their personal little world. The world electricity generation,transport, water supply and food production networks can't be replaced at smaller scale: internet and communications that glued the people together would be replaced by slower methods and disconnect the world. They are even unlikely to survive without modern air conditioning and clean water, which will disappear with electricity - even if electricity exists the new owners of plants will dictate its prices and availability. A few post-apocalyptic novels touch the idea of elite emerging from bunkers totally unprepared for the disaster world they avoided, until the resources run out.
