whats worse onaas mammon or onaas Devarim?
According to your paradigm mammon is worse since it has a worse punishment.
Yet see Kitzur 63:1
וּגְדוֹלָה אוֹנָאַת דְּבָרִים מֵאוֹנָאַת מָמוֹן, שֶׁזֶה נִתָּן לְהִשָּׁבוֹן וְזֶה לֹא נִתָּן לְהִשָּׁבוֹן, זֶה בְּמָמוֹנוֹ וְזֶה בְּגוּפוֹ.
Precisley BECASUE there is no ability to pay back makes it worse. and violating a body is worse than money .
and that is regarding “mere” words. al achas kama vekama our discussion
