He is posting because he does care.
I probably meant something different.
What I meant is just that one of the main purposes of a GC is to free
programmers to manually release memory, this makes many other things simpler.
If you keep a way to manually delete an object in a GC-based language then the
programmer has to use care, to avoid memory leaks, etc.
In Python there you can do:
del x
but it doesn't deallocate the object x, it just decreases by one the reference
counts of x (and removes the corresponding name in the current scope), this can
lead to the deallocation of x, but it can also happen later. There is no direct
command to directly delete an object. So you need less care.

I probably meant something different too and also remiss of me
to leave out a few smilies. :-)
"has to use care, to avoid memory leaks, etc." Yes and presumably
"etc" includes not attempting to delete anything more than once.
