O365: Why archive?

Back on Domino we had a general policy to archive all email over x days old. The archive email went to a different server with disks targeted for the archive market.

When you're using O365 and your servers are all in the cloud what reasons are there to archive?
The only reason I can think of is if your email file gets to a certain size it hits an O365 limit. So you archive off the older stuff to archive file(s). In Domino it was no big deal to open your archive. In O365 you have to have this super desktop license to open up your archive, or use the web client to view your archive. The VP of IS put his boss on the limited client so that he can experience what the general population goes through (deny my budget, will you?). Honestly it was a surprise to find out the difference (and it ain't exactly chump change).

We have one user who isn't going to get the super client but his mail file is only around 4GB. 50GB is where you start running into issues. So he said why can't he just be exempt from archiving and keep it all in one place? Initially I was against it but I decided to at least look into it.
So, why should he archive?
