A phrase in the English language I always get a kick out of hearing.

"because that would make sense" is usually used as a sarcastic explanation as to why something that is sensible, logical, and good is not acted upon or implemented as policy, etc.

For example:

All those 300 or so Linux boxes are not behind a firewall because that would make just to much sense.

And of course, one can always add the f-word for more seasoning.

An alternative phrase could be:
... because that would be the right thing to do.
