Spacex rescue mision

SpaceX will be first "agency" that will have due to reusability Falcon 9 and Dragon2 option almost instantly launch rescue mission, to stranded crew on LEO and beyond(for example Moon  orbit and surface).

They've been trying to launch this Iridium rocket "almost instantly" for like a week now without success.  ;D ;D

Re usability does not provide more responsive launch. In fact, it may take more time to refurbish a first stage than to build a new one.

reusability doesn't make it viable, having hardware available. A robust production line is just as much an enabler. 

Also, even though hardware is available doesn't mean mission planning is.  There has to be a concerted effort to have products on the shelf to support a quick mission call up (rescue mission vs a satellite delivery mission)

And it still won't be instantly, it still takes a matter of a couple of weeks to prep a mission.

It's kinda hard when you're doing a RTF mission and mother nature isn't cooperating

In my humble opinion, the way to provide "rescue capability" would be for NASA to fund the construction, storage and maintenance of rescue vehicles.

NASA on several occasions had a backup Shuttle on the pad ready to go in case the primary vehicle had an issue on orbit. For example the last Hubble servicing mission: http://www.space.com/6597-rare-sight-twin-shuttles-launch-pad-time.html

For the reasonably forseeable future, that's the only way a rescue would be feasible: have the mission planned and hardware ready to go ahead of time.

Only relation between reusability and rescue missions is indirect one - it would be easier/more feasible to do things like standby ready to go missions Shuttle-style, since it would be cheaper.
Be successful.  Then tell the haters to (BLEEP) off. - deruch
...and if you have failure, tell it anyway.

Yes.  Having a busy refurb line means that likely there will be several boosters "almost ready to go".
With expendables, only if you're lucky.

Second stage will be an issue for the time being.

Put a different way - reusability alone doesn't help.  Reusability and a busy launch schedule - definitely does.
