I just got a set of used wheels..the threads for the lockring are stripped. Is it safe to ride no lockring on the track?

probably but some tracks may not allow it.

There's a theory out there that no matter how hard you try you can't backpedal hard enough to loosen a properly mounted cog if you don't have a lockring. But if the unthinkable should happen then you'd probably better know how to brake using hands and heels!

Where is that theory from? You can definetly do so you just won't on the track since you don't have to stop fast.
It would appear that the wheels were for breaking too I think stripping threads count as breaking right.

If you're on the track and slowing hard enough to spin off the cog you already have much bigger problems.
I know more people who have stripped cogs off the threads pedaling forward (at least 2) in standing starts than have spun off cogs pedaling backward (zero).

So far this season I've actually seen two riders spin their cogs off on the track. Both were former or current messengers, so they were used to backpedaling. On the track, you really don't backpedal -- it pushes you back into the front wheel right behind you. Rather, you modulate your speed and steer to avoid problems. So the answer is probably that a good track rider has a low likelihood of needing the cog, but a messenger riding on the track is more likely to need it until he/she learns good track habits.

Loc-rings make great keychains!
I second and third the opinion above about spinning one off. My track bike sees a buttload of road miles, efforts and instances where I HAVE to slow down. I never use a loc-ring. If you have a little grease on the hub threads and tighten it properly you shouldnt have a problem.
We had a few cases on cheap track bikes my shop sold and on some cheap wheels we sold to posengers where the cog threads were stripping. After looking over the hubs for hours we relized that some of the cheap cheap cogs that come OE on most price point track bikes (1/8 and 3/32) dont have as wide of thread. Meaning there is enough of a gap between the cog and loc ring to let the cog move. It then runs into the loc ring and can work the threads off. Even then, cheap cogs have poor threads. I was amazed once when I ran a cog over a brand new BB Tap (same thread) and it took materiel off.
Wrenches lesson of the day: Spend the extra $5 and buy good, steel cogs, put a little lube on the threads and make sure they're tightened properly!

It's true that some cheap cogs have poor threads. Sometimes it's cheap metal. Are you sure that the thread pitch was the same? Cogs come in different thread pitches.

Im well awear that there are a few cogs that come in differant pitches. But thats mostly old days crap. Spite that theres 3 popular loc-ring thread pitches 99% of track cogs use the same thread now.
For sake of control reasons Ill give the experiment report like it was a science class.
New out of box Dura-Ace cog 15t threads freely onto a brand new not used yet BB tap, The same cog also threads easily onto a brand new Suzue Promax, new formula hub and used Dura-Ace 7710. Some resistance on a new KK hub.
New out of box Dicta brand cog 15t(actualy came with my bike) instantly encounters resistance on formula hub, suzue hub and KK hub. The fact it didnt get 3 threads in nicely caused me to stop before I damaged my own and a customers hub. It was "chased" when run over the tap.
Prognosis: cheap steel cogs chase their way onto nicer hubs pre-damaging the threads. Bottom line in my opinion is if your going to spend the dogh for some nice hubs or areo wheels, spend the extra and use good cogs too.

I always ride without lockrings on the track. If they come with my wheels, I take them off, I think they're pretty unneccessary. If your a courier and plan on locking up your rear wheel through traffic all day is a different story, but for riding on the track, I would not worry about it at all. And I've gotten that advice about lockrings from one of the most knowledgeable people about the track in the country. So ride the wheels

Any of the people saying it's not very common must not be sprinters. Some of the more aggressive riders use tactics like false jumps to trick another rider into leading out. Not just in sprints, but scratch races and points races, etc. I have seen cogs spun off in sprints twice in my life. Once was after a race and the guy was trying to get off the track before the first turn (why, I don't know), and the other was in a match sprint where the leader was desperately trying to get the follower to take the lead during the first lap (no track stands allowed).
I would agree that it's rare, and unless you use extreme movements in your tactics, you're fine. I also don't see it as a safety problem since both riders were fine, just annoyed that they had to coast back to the apron.
