Yes all valid concerns. Part of your first point is mitigated by the need to link private keys to tax returns or other documents such that just issuing new keys would not be possible and would make fraud obvious.

And presumably it would not be possible to intercept private keys in transit as they should never be transmitted.

However even when voting with your own private keys voting at home or under the watchful eye of someone else will yield different results than voting in a private ballot box.
I am sure there are many people who lie to their significant other about their voting habits.
