No, using `point-min' is wrong.
`point-min' usually return 1, so you won't notice any difference. But
if the buffer is narrowed, point-min returns a different number ...
making the effect of pressing delete quite unpredictable.
There's also the built-in `delete-selection-mode' which does something
similar.
