Only have as many building stacks as there are players

[Brian Hazzard]

In the real game, you have 1 stack of 7 buildings for every player participating. This is how the game keeps it tense for a lower number of players.

I'm not disagreeing, this makes sense, but where is it in the rules? I only see this:

With 3 or 2 players, only 2 of the 3 places: tool maker, hut, and field may be filled in each round. The third place remains empty. Naturally, the empty place can be different in each round.
With 3 players: on each of the places: forest, clay pit, quarry, and river only 2 players may place people in each round.
With 2 players: on each of the places: forest, clay pit, quarry, and river only 1 player may place people in each round.
All remaining rules remain unchanged.
