Reasonable question. Yes, in that case, the house probably would have been fine. The lateral force on concrete pillars, even from tremendous volumes of water, is fairly easily withstood.
The very first thing in TFA is a photo of where one of the pillars was ripped from the foundation. If that happened because of the force of the water against the house on top of it, then it could also happen when a tree or other large piece of floating debris hits it.
> even from tremendous volumes of water, is fairly easily withstood.
Physics is not on your side here. if it was just water, then perhaps, although I am sceptical given how much force is generated by 10foot of water moving at 18 mph, which is ~6metric tons of lateral force. (assuming 1m2 cross section.)
Thats before any flotsam gets attached increasing the surface area.
Sure you could build something to withstand that, but could you afford to build it?
