1. Game Balance:

- Limiting players to one Chance or Community Chest card per turn helps maintain balance in gameplay. If players could draw multiple cards in a single turn, it could lead to excessive advantages or disadvantages, skewing the game dynamics.

2. Encourages Strategic Play:

- By restricting card draws, players must think strategically about their moves and the implications of landing on these spaces. This adds an element of anticipation and planning, as players consider the potential outcomes of their actions.

3. Prevents Overwhelming Effects:

- Many Chance and Community Chest cards can have significant impacts on gameplay, such as granting money, forcing payments, or altering positions on the board. Allowing multiple draws in one turn could create chaotic scenarios that disrupt the flow of the game.

4. Maintains Game Pace:

- Having only one card draw per turn helps keep the game moving at a reasonable pace. If players were allowed to draw multiple cards, it could slow down gameplay and extend the duration of each player's turn unnecessarily.

5. Simplifies Rules:

- A straightforward rule regarding card draws simplifies the overall mechanics of Monopoly. This clarity helps new players understand the game more easily and reduces confusion during play.
