IMO posters simply dont get the economics of new car ownership
and the transition from the first buyer to the second buyer.

From the top down:
(a) New EV buyers are normally professional middle class buyers with
an ABN or Government departments and "Not for Profits" that but tax free

(b) While 2nd owners are normally individuals who do not qualify for tax concessions .

Your depreciation argument is from a 2nd buyers/working class point of view
while the business argument for EV is about the overall cost of ownership
for the first owner optimising tax concessions etc.

This is why BEVs are mostly bought new by businesses via a Novated lease
system or tax free Government departments etc.

This is exemplified by the Novated Least chart below.


NB: The business argument above includes full cost of ownership which includes depreciation.
