Can I alias rm to trash-put?

You can but you shouldn't. In the early days I thought it was a good idea to do that but now I changed my mind.

Although the interface of trash-put seems to be compatible with rm, it has different semantics which will cause you problems. For example, while rm requires -R for deleting directories trash-put does not.
But sometimes I forget to use trash-put, really can't I?

You could alias rm to something that will remind you to not use it:

alias rm='echo "This is not the command you are looking for."; false'

Then, if you really want to use rm, simply prepend a slash to bypass the alias:

\rm file-without-hope

Note that Bash aliases are used only in interactive shells, so using this alias should not interfere with scripts that expect to use rm.
