A strong, solid tree with deep roots will neither break nor be uprooted when a strong wind blows. A weak, fragile tree with shallow roots will either break or be uprooted when a strong wind blows. It is therefore not necessarily a bad thing for strong winds to blow.
Likewise, a solid house with solid foundations and a flimsy one with flimsy foundations: one will easily survive an earthquake, the other will not, and let not the earthquake be blamed for helping us distinguish the solid houses from the flimsy ones.
