A unicycle and a hula hoop have similarities.
As I said, the distinction matters. The argument by metaphor in your previous comment is off-base.
Feel free to address concretely what I wrote in my previous comment.
(Though I have doubts about the quality of any insights that might be offered; no one referring to Wikipedia as "Wiki" is informed enough about Wikipedia to be informative about it.)
Well, the wiki’s policy is irrelevant. Or only 50% relevant.
I see that the policy tries to provide some “spirit of the law” and/or hints to avoid edit wars and such, but evidently many follow the policy only in letter and just know what not to mention, i.e. to not trigger the policy. (instead of rejecting edits with “I own this” or “I know this better”, edits get rejected with “citation needed”)
> As I said, the distinction matters.
I see you sincerely believe that it does, but I’m of different opinion.
People in any group form a hierarchy, and have (frequently unwritten) “traditions”. And those are features, not bugs.
Hierarchy is not necessarily strict or formal, but it helps with coordination.
“Tradition” is the actual way how things are done. “Tradition” can be changed by policies, it may even implement the policy to the letter, but it always encompasses more than the policy contains. Because it’s almost impossible and most undesirable to have policies for each breath we take.

Somebody has older account then me here and is feeling authoritative I see. Thanks for good practical illustration.
Which interactions exactly are possible depends on the particles & forces involved, and further conservation laws for quantum numbers (e.g. charge) that the force obeys.
TL;DR Turning a single massless particle into a single massive one is not possible, you always need at least two.
(What conservation law would it violate?)
