Your laptop, maybe. It sounds like you understand security, which is good. Not everyone does. I'll give you an example:

I have a picture I like to use in my presentations where I was at a mostly-empty family restaurant and the person sitting next to me (alone) had their laptop sitting out and went to the bathroom without even locking the screen. In 15 seconds I could have popped in a USB drive and copied all of his SSH keys (and more) without anyone ever noticing. It could have been done before he even reached the bathroom door, let alone came back. I don't think you would do this, of course, but some people do. And your coworkers might.

On top of that, about 25%-30% of security incidents are caused by insider threats. Considering how easy attacks over the Internet are, that's an absolutely massive number. Even if your laptop never leaves your desk, it's entirely possible someone within your company might want to do some harm to you or the company and it might be the desktop support technician hooking up your new monitor while you grab another cup of coffee.

Your point about what's riskier is completely true: if you have Internet-facing servers using passwords, stop that and use keys. But when you do that, you need to study up on the new risks you may not be aware of. Security shouldn't just be a curtain you close. Companies/people who don't understand this love paying me shitloads of money to explain it to them :)
