Jesus and the money changers

[Aractus]

The money changers invented a way to extort money from people who came to worship God at the temple.

That's not the case at all. They provided legitimate services for legitimate needs, for instance changing the currency to the only accepted one that could be offered in the temple. And by offered I of course mean for taxation. Jews who traveled long distances would find it convenient to purchase sacrificial animals instead of bringing them along on the journey to the temple. Jesus doesn't accuse them of dodgy business practices as you claim, however it is made clear that after he drives out the money changes he himself sits in that spot and begins teaching. It is clear that, right or wrong, Jesus believed that the space was for teaching the Law and that purpose trumped the purpose of the money changers.
