Honestly, some people's hobbies.

At 50Hz the skin depth in copper is 9mm and his cables seem much thicker
than twice of that. What a waste of metal.

Best regards, Piotr

Have you tried sourcing hollow cable?
Anyway, much worse things happen at RF.

Have you tried braiding thinner cables or parallelising more
secondaries, which he has already done?

Best regards, Piotr

Flat mag wire. (it is actually rectangular with tiny rounded
corners). Not cheap and very rigid.

OR...
I would hand 'braid' like #12 high strand count SPC wires to get
some Silver in there. Put about 16 together to approach the guage of
his welding cables. Leave the insulation on (teflon). Parallel a
bunch of those together and crimp AND solder the lugs. Allows them
to be set tighter onto the core as well. Hell, put the primary on
top of that. That would be like a high efficiency, LITZ configured
secondary.

Air filled hollow copper wire is called "copper pipe"

but it doesn't need to be hollow, just thin, so use strap.
