So since ODBL and CCBYSA are not compatible, why would it be less of a source of possible conflicts and infringements of Wikipedia's content license to use ODBL instead of CC0?

No you cannot: CC-BY-SA is not intended for data, so regarding data you should never use any CC licence (pre-version 4.0, v4 will address database rights) other than CC0. That's why if you want BY-SA conditions, the good choice is ODbL which was created by the Open Knowledge Foundation exactly for this, a share alike licence for opendata.
Like I already said a few months back, I totally agree with Alex : using ODbL and therefore keep along the BY-SA choice that rules Wikipedia is the most logical choice. Mocing towards CC0 would be a source of a lot of possible conflicts and possible infringements of Wikipedia's content licence.

other way around.
Or else what do you mean with "compatible"?

I guess things would be far more easier if WikiData would choose a CCBYSA-compatible database license like ODbL. I can only repeat myself,
that
the OpenStreetMap community went through a similar discussion and
decided to
respect database rights and keep their data as clean as possible.
Because
they didn't want to take the legal risk, that after 5 years a big
company
like Google will sue them and so OSM might loose the work of 5 years.
I also think that there are two aspects in this topic: 1) the pure legal aspects and 2) how we (Wikipedia users) treat each other and respect the work of others. So the WMF might say: hey you European guys with your DB rights... bad luck that you invest all your work into a US hosted
project -
we don't care about your rights. Even _if_ this is legally not to be objected, is it fair against the users?
To make it clear: I'm into lots of list articles (streets and monuments) which contains lots of data. This content is licenced under CCBYSA
today.
The day when all this content will be expropriated by WikiData, is the
day
I'll stop my work for these Wikipedia projects.
