Oh sure, I agree with that completely
My issue is just that I think a combination of factors ends up with some worse results:
- You're required to disclose if there's any
- You're not prohibited from saying that there is if there isn't
- Anyone can sue you if they claim there is and you didn't disclose it
- It's cheaper to just assume everything's dangerous than to actually measure
I think that some of the labels are so clearly ridiculous that nobody takes them seriously, and that results in people not taking the _actual disclosures seriously_
The warning that "this bookshelf contains formaldehyde" - useful. "and it will off-gas for a few weeks, make sure there's good ventilation, keep it somewhere where there's good ventilation for a month before moving it anywhere where there isn't" would be even more so. It tells you what you have to do to use it safely.
"This may contain _something_ bad but we don't know what, we just don't want to be sued if we missed something" <- detracts from the first one. It just makes people see "califronia says..." and zone out. There's no actual information in it, there's no instructions on how to make sure it's safe, so if you're already going to get it anyways, it doesn't change what you're going to do anyways...
