However, sets are timeless, but the "shared mental concept" is not. It
started at a certain time. It has a creator, and other properties that
would not apply to a set. (012)

I would define a "shared mental concept" as a temporal massless entity
which can have an unlimited number of physical objects and events
representing it, such representations may be more or less accurate and
precise. Some representations may only represent part of the concept;
others may incorrectly represent certain parts of the concept.
Representations may be of different forms: physical objects to be read;
physical objects to be projected by physical devices, events of people
acting out events which are part of the "shared mental concept", events
of people reading text of the "shared mental concept", etc. (017)
A "shared mental concept" would have subtypes such as accounts,
agreements, obligations, laws, and games (such as Chess). Each of
these subtypes of "shared mental concept" would have a number of
different relations which apply to them and rules for such relations. (018)
These various features (partial representation, incorrect representation,
...) do not seem to me to be possible features of sets. (019)
