"Basically, the value is the ability for two person to communicate on a specific topic in which both due to the context of the statement have a mutual understanding as to the words meaning."

The mutual understanding of the difference in meaning and use of such terminology needs to be understood before any meaningful conversation can be had.

"My question is what gives any profession the right to capture a word, define it, and forbid others from using it in another context."

A reasonable question ...I do not have an objective answer for you.

In thinking about it more, the practical solution is to recognize there is a difference, make it understood to those involved in the discussion that there is a difference, and make it known what the difference is. For example, in cross, if the lawyer characterizes your determination as "just a theory," an effective response would be to explain the SM in the context of hypotheses, theories, and laws. Tell the jury that his/her characterization of his determination is misleading and false.
