The actual town wealth will only be complete, if it counts in the placed items in your town.
Since there is already difference between natural and player placed blocks in their data, `/wealth town` should count the player placed blocks, check their `/value` (if no value data found, then wont add anything to the total), and add them to the value of the town.

The command output rn:
The town has a total wealth of .
- is held in its bank
- is held in its residents' balances


How I'm suggesting it:
The town has a total wealth of .
- is held in its bank
- is held in its residents' balances
