Like I said, the law could use some work. They jump to legal consequences way too fast. Other options listed in the article can be effective - this year, a kid at my school was told that if he didn't get his butt to school consistently, they wouldn't sign off on his learner's permit for driver's ed. It worked.
The article does say the school has a few exceptions for chronic illness and emergencies, and I missed that when I read through it last night. I totally get the extenuating circumstances. Coffeehorse - I'm sorry you got so sick, and I'm glad your teachers took you aside and started streamlining things.
I hate missing school, personally, because it takes so much work to plan for being gone, and then there's a crap-ton of work to catch up on when I get back. I typically miss as little as possible, but I've had years where I was gone a lot. (One year my wife had multiple surgeries and there was some other family stuff going on - I missed more before Christmas than I had in multiple years before that.)
High absenteeism affects so many things, but my frustration isn't with people who are legitimately sick. It's with family after family that takes advantage of weak attendance policies.
