Research good.
Legalism bad.
Legalism and corruption are what Christ cleansed from the temple. Not greed - which is mentioned in none of the gospel accounts. (Don't fall prey to the mis-teachings of the Left. Christ is a free market Man.)
You obviously enjoy specifics: what specifically is listed as the marketed products Christ drove out by whip?
Household items maybe, pots, pans, Paula Dean knives? No, that wasn't it.
Ham sandwiches, beer, popcorn, a pack of smokes? Nope.
Hymnals, loin-girding belts, Herod bobble-heads? Again, no.
It was sacrificially 'clean' animals - sheep, oxen, doves. A dark convenience for the hip worshiper on-the-go. The vendors were in cahoots with temple bigs - or they would not have been there.
They were essentially selling salvation. Which is kinduva no-no already. But hawking salvation in the presence of the Savior?... they were fortunate He used a whip.
To both the temple authorities and the temple-goers, the act of sin-cleansing had devolved into a legally-correct but faithless schedule.
That has to be understood. Or you won't understand why Christ acted as He did.
Consider why He called them 'thieves'.
Again, not because of 'greedy' high prices or any such thing. Because they were selling snake oil - whatever the monetary value, it does not work as advertised.
Don't let any denomination nor day can keep you from Christ. He did not rent the veil to clear room for more of Legalism's tables.
Keep up the good research.
And pray you don't let dates become your doves.
The reason I included greed is that the high priest ordered that only Tyrian shekels would be accepted for the annual half-shekel Temple tax. They contained a higher percentage of silver, so the money changers exchanged unacceptable coins for these shekels. Of course, they extracted a profit, sometimes much more than the law allowed.
Shalom
