But you can turn most of these offloads/optimisations off if you want (though you can't force checksum generation for loopback). The same goes for tcp_friends.

The lack of checksums is a very trivial issue. The lack of segmentation is also irrelevant -- it appears as an interface with an infinitely large MTU. The packets captured on "lo" are still basically valid TCP packets.
Not seeing any packets and being unable to debug network interactions *at all* is a huge deal compared to these.
