Jesus wasn't concerned with a little commotion. It was that the poor and reverent coming to worship at the temple were being cheated, and thus his comment that they had made his father's house into a den of thieves. To buy a bird or animal for sacrifice, one had to exchange his local money for whatever currency was used in Jerusalem. The dishonest money changers were not giving fair value in trade, and the high priest was allowing them to flourish as he received a cut.
In Martin Luther's letter to the Pope asking him to halt the practice of selling "get out of purgatory passes", there is the distinct implication that the Pope allowed it.
I imagine that was part of Christ's zeal for His Father's house.

You are presuming that Luther "implied" anything of the sort. The practice was not universal, first of all, but relegated to one section of Germany. Next, Indulgences are not "get out of Purgatory passes", but rather, penance that relieves the punishment due to the temporal effects of sin. Some people could fast, others would pray, and others would give alms, to each their accord and position in life - given to them by God, no doubt. In any case, they are witness to the sorrow and contrition of the penitent. Were there abuses? Certainly. Was Luther correct in bringing the attention of this to the Pope? Sure. Was this a reason to leave the Church established by Christ? No.
