There is a way to stop these.
For the discussion, let's rule out the scenario of a competitor being able to pull off a CCA that is human driven. For example, a competitor e-mails a hundred of his friends to all sit around on their computers, take the time to read the Ads on your web pages, and then click on your site's AdSense ads. This is a very unlikely scenario.
The competitor would have to use a fairly sophisticated bot. He can't do it himself, because there would be a concentration of clicks coming from one or a few IP addresses which would be a dead giveaway.
A bot that spoofs IP addresses, or hops through open proxy servers would be necessary.
Every so often Google, let's say 1 out of 100 times, Google serves ads that, based on the content of your page, are known to have an absolutely terrible CTR.
If the CTR for these terrible CTR ads jumps on your site, they know it's a bot doing the clicking. They would know this, because only a bot would click on it because bot's can process text, but they don't understand the content.
Second challenge. How does Google know they are serving up 'bot test' ads that have a terrible CTR?
That's the easy part. The 'bot test' ads are the very same ads that Google is disabling on the AdWords side, due to a terrible CTR for the AdWords advertiser. It's a self-generating system.
In addition, since the ads are real ads with proven bad CTR's from actual AdWords campaign data, it would be almost impossible for a highly motivated and highly skilled competitor, to try and modify the bot so that it checks the ad keywords for relevancy against the web page's text.
Even though the 'bait ads' have a terrible CTR, they were still written by some hapless AdWords advertiser that was trying write a relevant ad. The ad just failed, that's all.
If the hostile competitor is reading the ads himself, and spoofing IP addresses himself, how does he know if the ads have a terrible CTR? He can't. Only Google knows this from having actual data from thousands of AdWords impressions across multiple AdWords advertiser campaigns. So it even stands up to the human driven CCA scenario.

1) Much of the program's expense would be borne by publishers, because every "bait ad" would mean one less revenue-producing ad.
2) On low- to moderate-traffic sites, the sample size of bait ads would probably be too limited for statistical accuracy unless bait ads were a significant percentage of total ads served.
By comparison, websites in the same niche are scarcely in competition at all, from an AdSense point of view, because they don't compete for ads or revenue.
