That is a good point, but also a feature in my view. I see my chromebook as a mobile workstation, so more or less everything on it is backed up in a git repository, cloud storage, that sort of thing. ChromeOS automatically restores extensions and installed Android apps, and I usually keep builds of software I use in crouton on separate external flash storage; 16-32GB of internal storage isn't that much when you have to build from sources because ARM binaries are still fairly rare.
So an inadvertent wipe is really just an inconvenience of 30-60 minutes, and if it's a border patrol or TSA agent you can then have fun acting all indignant at how they broke your device and you lost so much work and your boss is gonna kill you and you want to talk to their supervisor right now.
The lack of hardware security is a consideration, but frankly if your device is handled by a malicious actor outside of your control, you're kinda screwed anyways.
