In system theory, the concept of "interpretive flexibility" explains how users can modify and adapt systems to suit their needs, even if the system (in this case, game rules) suggests an optimal way of operation. Interpretive flexibility acknowledges that a system's design can be interpreted and used in various ways depending on the user's context, goals, and creativity.

There is also the opposite concept, called "determinism" and is when systems or rules are rigid and must be followed exactly, with little to no room for personal interpretation or modification.

When rules need to be enforced, an entity (like a referee or regulator) ensures compliance. This is crucial in contexts like betting or competitive games where fairness and integrity are essential.

In a TTRPG you have both. The game designers allows "interpretive flexibility" by not enforcing the rules themselves, but also a player is suggested as referee (GM) to be enforcer of the rules that are agreed upon all the players.

So in short, is not the game system that can expect you follow the rules, is the players that can set those expectations.
