I'm going to slightly disagree: the players can choose to make stuff that isn't directly related to adventuring important, simply by deciding that their character cares about more than just adventuring. But if no one cares, then no one cares. And if that's happening at your table along with no magic item shops - then yes gold doesn't matter once you got yourself the best armor you can buy.Very few of the things the rich buy in our world are by default considered important to adventurers. You as the DM have to make them important, and the players have to willing to go along or suggest their own ideas. The text should be helping a lot more than it does.
I'm not sure this is a failure of the system. It makes money, as a motivation, optional.
