(Like "wealth" through a large in session haul)

A big pile of Cash is not the same as the Advantage Wealth.
The benefits of Wealth require point expenditure (or the advantage could be gifted by the GM like any other Advantage - Rank granted by a Patron, Unaging granted by a God, etc.

Having a big pile of cash does not 'require' you to spend points on the Wealth Advantage - with 2 possible exceptions: Dead Broke, and where you have a Job of a higher Wealth Level.
If you don't spend points to increase your relative Wealth level, then those characters who are Dead Broke will 'lose' their money (the cost of a -25 points Disadvantage is being hosed by fate/GM); and those with a Job from a higher Wealth level risk losing their Job (the rules don't actually say that, but its a logical resolution to the situation).
