More freedom by virtue of having more money? Above a certain level of "enough" money, money becomes less and less important. Or it becomes an obsession, in which case more money takes away freedom. Falling into this trap is tragic if you ask me.

And there will always be sometjing you want but cannot have, regardless how much money have. E.g. art, the Mona Lisa will never be up for sale. Or some other unique piece of art. Accepting that fact makes you a happier person, or at least doesn't hurt.
