If the kernel doesn't respond to syscalls, nothing happens.

I said Linux was pretending to be Unix and it is: it emulates the interfaces well enough that it runs Unix software from the 1970s. Are you trying to convince me that it does not present a Unix interface to the software it runs? Because it seems that you are trying to make the case that it is not a complete operating system, and that would be unrelated to what I said.
