I strongly suspect that it is unreasonable to expect people to actively apply x-rationality on a frequent, conscious basis—to do so would be to fight against human cognitive architecture, and that won’t end well.
Most of our decisions are subconscious. We won’t be changing this. The place of x-rationality is not to make on-the-spot decisions, it’s to provide a sanity check on those decisions and, as necessary, retrain the subconscious decision making processes to better approximate rationality.
