Final answer:
When the percentage of the economy based on decoupled activities reaches a threshold or is dangerously close to it, the floors are at risk of losing pick capacity.
Step-by-step explanation:
According to the information provided, it is suggested that limited resources essential for survival would not fall much below 10% of the total economic scale. This is based on the assumption that physical resources cease to grow in scale within a century of physical saturation. Therefore, when the percentage of the economy based on decoupled activities reaches this threshold or is dangerously close to it, it can be inferred that the floors are at risk of losing pick capacity.
