Why do you think that common pg-users doesn't care about their data?
Did I say that?
Also why do we have wal_level=minimal fsync=on and other stuff?
To make certain garantees that data is by default durable.
What I'm saying is that everything is a compromise, cost/benefit. The
universe might explode tomorrow but the chances are slim, so no use
preparing for it.
Those caring enough probably use checksums, battery-packed RAID etc.

Wal is not durable without crc in it. But we have by default crc in wal
and not in data files.
