If you bought a $100k+ ICE car and 250,000 hard kms later blew up your motor and went to the dealership to buy and install a brand new long block, are you not expecting to pay tens of thousands of dollars? You have to compare apples to apples.
I found an M4 motor on "Black Friday sale" lol, sold by a 3rd party vendor not even the stealership: $25k CAD, not including install labor. What would that labor be at BMW? Like $10k? At the end of the day, you're fucked nearly just as hard.

The guy should've skipped the dealership and just rebuilt his existing pack. Maybe it was just a bad module:
