The idea isn't to benefit OSM, it is to benefit map users. By which I
mean the user of a given instance of a map derived from OSM data or
graphics.
If you are holding a map then being able to copy and modify it is more
useful than being required to send data back to OSM.

Based on the success that small Free Software projects have had I would
say that you don't need a giant budget, just a friendly lawyer.

I would be surprised if this is the case. Sending the PDF to the print
shop should count as distribution because they have to take a copy from
you. A good comparison is font licencing, where you are not allowed to
send a copy of an unusual font that you have used to a print shop. And
GPL-3 has been specifically modified to ensure that subcontractors
working on code doesn't count as distribution.

If I ever meet anyone who actually believes that you have to give
someone your BY-SA t-shirt if they ask then I will get a photograph of
myself wearing it next to them before giving it back. ;-)
