Assuming you mean replacing the actual author's address with the
list's address, that has the cost of breaking the way mailing lists
have worked for 30 years, and in particular making replies to the
author unworkable.  Many people would strenously disagree that this
"eliminates all problems", but merely replaces one problem with
another.

There are other workarounds with different costs and benefits, e.g.,
the one I use that rewrites DMARC'ed addresses into local temporary
forwarding addresses, in my case in the trendy dmarc.fail domain.
That lets people keep using lists the way they have but requires more
mail system hackery than most list managers are able or willing to do.

Again, this has been discussed at great length here and on many
mail-related lists.  Please see the archives.
