Then you are guaranteed to have it break unless you spend $1000 every 5 years on changing a belt.

Not exactly. Most belts tend to exceed the OEM schedule. In a non-interference engine, it is cheaper to wait for the belt to snap, then get towed in, versus replacing the belt when you are supposed to.

As for the price of t-belt replacement, usually it costs far less than $1000, but typically only if the engine is an inline engine with a decent amount of accessible space.
 
5 years is also a rather pessimistic number, but it makes for a good story I guess if you want to build a case against it. Most mainline manufacturers recommend a change every 100,000 miles or so. Some include a time interval as well; Honda figures 15,000 miles/year, and their timing belt change interval is 105,000 miles or every 7 years. An independent shop can do the job for $500-600. You can do it yourself for half of that.

And as this thread correctly points out, a timing chain is not a guarantee of reliability. In general, timing chain systems are designed well. But they aren't always...

Aside from the middle picture, the other two look like motorcycle engines. Considering how highly strung these engines are and the RPM range they operate in, I would consider your post a compliment to timing chains.
