Right.  At best you want to kill a buffer.

If one wants to use a command like that, one can always say
M-: (erase-buffer) RET

I also think that it should not be a command.  If you need to erase a
buffer for whatever obscure reason, you can clear it with
M-h C-w

It would at best make marginal sense in, say, a shell-buffer which
you find has grown too large for your taste.  But even there, you
would want to have it remove things like read-only prompt strings.
