MEV is a very real threat we need to think about and consider mitigations for. Within a few halvings, it will likely be rather problematic.
Lack of free market in Bitcoin is most problematic. As a side note - noone here was able to deny to this obvious statement:
There is no free market between active users (wanting stakeholders to pay for the network security) and passive users (wanting transacting users to pay for the network security)
But MEV is cancer too, if would only appear in Bitcoin, like it already has appeared as _ pure pathology _ in Ethereum.
