Agility is a quality and a relative assessment

I prefer to frame "agility" as a quality. It is a relative assessment. It is not a binary assessment - not a 1 or or 0.

Use of the word "more" in the phrase "while there is value in the items on the right, we value the items on the left more" from the Agile Manifesto supports a relative assessment approach. 

Agility is associated with the power of moving quickly and easily. It is associated with the ability to think and draw conclusions quickly. Often, improved agility correlates with improved reaction time. Synonyms include nimbleness and quickness. The German word “behedig” is translated as clever, dexterous, and skillful. Behedigkeit is translated as agility.

Often, agility is a quality that enables someone to accomplish the desirable. Typically, through training and deliberative practice, one's agility can be improved.

I prefer discussions that reinforce the concept of agility as a quality and a relative assessment. When agile is associated with qualities such as clever, dexterous, and skillful, it is a quality that is desirable for nearly everyone.

Agile is a Set of Values

Stated another way, agile is a set of values, not a process. There is not a definitive, single Agile method. A mix of Agile methods are used to support agile values.

The phrase "Agile requires" is not in the Agile Manifesto.

Better Results

Today, I noticed that someone posted "Once a team installs agile..." This paradigm is different than mine. 

Although some may insist that they can install agile, I have found that better results are obtained when agility is developed by investing in individual contributors.

According to Boyd in later versions of Patterns of Conflict, the ingredients for vitality and growth include insight, orientation, harmony, agility, and initiative.

One can evolve and exploit agility as a basis to win.
