Until you get hit by a vulnerability that was patched four years ago,
but you didn't get the update. Now your server is down - or, worse,
has been compromised. What's the economic cost of that?

You might choose to accept that risk, but you have to at least be
aware that you're playing with fire. Laziness is not the cheap option
in the long run.
