Even blocked-off parts aren't risk free. Anyway, riding in a blocked-off part isn't an option here (so talking about blocked-off parts is irrelevant).

This isn't always true. In this case, it appears to be a relatively slow road.
It's not certain that riding in the door zone is safer (the magic green paint doesn't, by itself, make it safer).
Experts in bicycling safety recommend not riding in the door zone. So, your notion that it's safer to do so (in this case) runs contrary to standard advice.
I'd be very surprised if anybody here says you should be in the door zone.
