If you want to be taken seriously it is up to you
to tell the world what is wrong with Maxwell-Lorentz,
and how these equations must be modified.

It is entirely possible that Banjo stumbled across that apparent
violation of momentum by momentum being carried away by the
electromagnetic field.

 If the momentum is carried away by the electromagnetic fiel
there is still momentum conservation.

Exactly. I just allowed for the extremely remote possibility he detected something relevant. Almost certainly, if he found anything he found the known momentum conserving electric field.

And photon drive really isn't a new idea.

Even solar sails use that effect (momentum of sunlight).

However, it suffers from the unpleasant fact
that  c = 300 megawatt/newton, in slightly unconventional units.

That is why what we are really seeing is sloppy demonstrations, it is very unlikely Aridam's experiments could detect that small effect. We won't know because Aridam's experiments are unreproduceable, insufficient detail to reproduce his situation.

 

But we will never know since he refuses to
produce a writeup in sufficient detail for someone to reproduce his
experiment, instead writing "Watch my videos!!!".

 There is of course no momentum violation at all.
Whatever seems to be missing must be taken up by the sources of the
fields.

Certainly. But we won't ever know.

(and of course I don't watch videos)

Smart. His videos are a waste of time.

 

Add his stubbornness that he insists this is something new that violates
Newton/Einstein/Maxwell rather than a known existing behavior, you do get
the incompetent tinkerer.

 Or the faker who thinks he is being clever.
There is no lack of videos showing really rotating unbalanced wheels,
rotating wheels with water bottles, and so on.

No lack of snake oil salesmen, even these days.
