People used to make similar arguments in favour of assembly language, ie. you can't be a programmer unless you can drill down to the bare metal and make it do backflips/squeeze every last bit of performance out. Now computers are faster, compilers are smarter at optimising and it's only really the case if you're doing hardcore kernel programming or writing a game engine. C, pointers and linked lists are going the same way as computers get faster still: they're not very relevant unless you're coding something in a specific niche.

And I've seen people who were the opposite of what you're saying - people who knew lots about low level C/Assembly stuff, but who couldn't write clean, maintainable high level code to save their life.

But to get back on the original topic - none of that is relevant to learning how to program. Loops, variables, data structures, managing state, functions and classes are more what you want to teach to start with, and are far more relevant to most programmers than malloc or linked lists.
