I also wonder why (apart from the charity sector) employees would be that invested. They don't get the financial rewards or the kudos that the founders do, so why invest their soul in someone else's problem?
Depending on their age, they might not know better. Young developers are sold the ideal of changing the world through passion, but still end up as just employees. I still remember the first time a company offered me options instead of an annual raise, and a more experienced coworker quietly informed me why they did that. My enthusiasm was quickly brought down to earth.

It is measurable in difference between the salary you would have received if you took a job before you worked for X startup and the salary you would have received if you leave and get a job after having worked for X startup.
Specifically I don't think points 3 and 4 are quite on the money - how much you care is often based on how much you perceive people care about you, and equity can be a pretty big signal of that. Additionally, I think people who care can be quite contentious.
Still, a good enough point to talk about. Apparent enthusiasm is one of the best things you can select for, when you see it, and it can make up for a lot of other things that might be lacking.
People who care will challenge the status quo. This is often deeply unpopular, especially in larger orgs. If you don't empower the people who care to make positive changes to the status quo, then those people will give up and stop caring. And then probably leave.
I've had the pleasure to be a part of a team where I was given pretty much free license to do as I saw fit simply because I cared as much about the product as the founders.
But hiring just one or two champions and filling in the gaps with mere enthusiasm or brute force is going to put an enormous strain on your champions.
