If your stuff scales to infinity your money burn rate also scales to infinity. A single server in a colo can only do so much damage to your wallet before it’s saturated.
On the other hand, if one could explain such causation, then I would be very interested in hearing about it.
Correct, but the effect on the wallet doesn't care if there is a causal relationship. And since my wallet is closer to me than a philosophical debate, the conclusion I reach in this case, is to move my site ;-)
