Again, I think it's the other way around. Civilian aircraft have
access
by default even to areas that on maps are designated for military
operations. The military notifies the FAA when an actual operation
in such an area is scheduled so that a NOTAM can be issued.
But -- correct me if I'm wrong -- typically a TFR will not be issued.

Restricted and Warning areas are HOT by default, times are published.
Military does not have to coordinate when as long as they are in the
published times.
Civil authority can ask the military to curtail activities when the airspace
is needed to route large volumes of civil traffic as when weather blocks the
normal routes.
Restricted areas could be for Army artillery fire, and not aircraft.
TFRs are not issued for R, W or MOA airspace, NOTAMS are issued when outside
of published times.

Civil (VFR) aircraft have access at all times except Prohibited areas, it
may not be smart to go in that airspace.
Restricted, Warning and MOA, sure.. go in if you want too.. it's your life,
and possibly the life of a military pilot you are risking.
I know violating certain Restricted airspace will be intercepted by chase
aircraft and met by federal agents when they land.
ATC will not clear civil IFR traffic into that airspace without coordination
with the military controlling agency.
The CIVIL ATC can close or pull back the R, W, MOA airspace at any time when
needed for civil use.

The Prez has opened up the offshore Warning areas to commercial traffic
(there are published airways in the warning areas) and made a public
announcement to the flying passengers, so it can appear that he is trying to
alleviate their travel delays.
