You’ll need to “substract the listed amounts of the Commodities needed for the Building from eir Commodities and may substract 1 from the amount of Periods listed on the World page”.
Only the ‘listed amounts’ that you’ll have to pay per period change, so I guess you could slightly lower the cost of buildings this way (not yet though; the periodical costs of the currently available constructions were designed with the possibility of this minor exploit in mind).
"Nomic is a game in which changing the rules is a move. In that respect it differs from almost every other
game. The primary activity of Nomic is proposing changes in the rules, debating the wisdom of changing them
in that way, voting on the changes, deciding what can and cannot be done afterwards, and doing it. Even this
core of the game, of course, can be changed."
