Is there something in the design of the bitcoin system that prevents this scenario?

1. The price of bitcoins drops by 80% (or some number) for some external reason.
2. The profitability of bitcoin mining drops significantly.
3. The number of bitcoin verifications drops significantly, causing
4. Additional drop in the price of bitcoins because transactions are not verified promptly.
5. Go to 2.

In other words, what happens if people stop bitcoin mining because it's too expensive? How will transactions be verified?

Eventually, the difficulty will drop. This will cause the mining to increase. This will cause an increase in the price because the verification problem holding the price down is gone.

There's another factor too -- once you've bought mining hardware, the cost of the hardware is a sunk cost. So long as it can pay for its electricity, you'll keep it running. A typical mining rig today produces Bitcoins worth about 60 times its cost of electricity (1W/GH/s). So the price would have to drop astronomically for people to stop mining.

It could, of course, significantly reduce the incentive for miners to invest in new equipment. But that will just keep the difficulty from rising. It won't significantly slow confirmations.
