Very much agree with you. Trams and metros fulfill different functions.

The “crazy” take in my opinion was equating keeping the tram system with not building metros, that trams “clog up the road”, and the dubious claims Musk could actually provide boring at ludicrously low cost.

Don’t get me wrong, the costs involved with building metros in the anglosphere are not in step with the rest of the world, but colour me sceptical about anything to do with musk, given all the quality issues with Tesla.
