I believe you were the first person to actually point this out to 
Satoshi. He replied by saying that 100GB per day is required to be 
processed every day by full nodes.

However I am confused by his explanation of server farms. Wouldn't at 
one point result to a small number of full nodes due to costs? Isn't 
that preventive of decentralization? I fail to understand how Satoshi 
would think that the entire world can connect to let's say 50 worldwide 
server farms and this would somehow scale and be considered 
decentralized. The point of decentralization is that everyone can verify 
all transactions. This is done by verifying each transaction against all 
transactions back to genesis by yourself, not by trusting 50 centralized 
nodes.

For all we can know, in 20 years from now only banking institutions will 
have the capital and benefit of running full nodes.
