Missions and more

I recently dealt with the issue of mission and it’s so not 2020.
The rich man’s emissary?? Who cares?
‘Not in the Torah’? Why (the hell) would the Jewish people make a donation to me? What’s so complicated here?
A woman sends a messenger to receive a divorce from a wealthy man (as in Yerushalmi, Tamman HaTorah won for her)?
I understand that it may be that in the time of the Sages, the public simply understood things this way. Either because ontologically, mission is the delivery of flaming balls of power from the holy messenger to the messenger (who happens to have no money and is not wealthy) or because people simply did not understand that mission belongs in these cases (if you are not wealthy, there is no certainty about your mission [?] Well)
But how does this relate to me?
My intuition says completely different things about mission.
I read the first ones on the subject and it doesn’t connect with me. I have to come up with all kinds of hypotheses about strange definitions (and they would do well to make all kinds of last ones… with the decrees of Scripture and peppered definitions) and it’s simply not relevant.
Is there anything to be done about it? (I’m sick of it, this is what they thought two thousand years ago and it will stick forever??)
Maybe I’m just annoying. I’m fed up.
