Right, so then why do you expect them to run a node in the future? In the case where nobody has a self interested reason to run a node, yes, Bitcoin dies. 

only a tiny fraction of bitcoiners care about that, most are just here for the money and don't care, don't want to understand how to run a node.

Future of bitcoin

At the end of the day, there is a self-interested reason to run a node: you want to be able to check that people aren't cheating you, that they really are sending you Bitcoin. The only way to to this without trusting some third party is to run a node that tells your wallet about the coins you receive. 

I figure people will continue to run nodes because it is useful.
