There is a point here but it doesn't actually matter that much in my opinion. Your point is if you're invested in your work there is no limit to how many hours you put in. I'd tend to agree with this saccharin made-for-TED description.

If I am paid $10/hr for my work I can't eat. My incentives are not aligned. You dont pay me enough to eat.

If I am paid $xxx/hr for my work but I am bound by NDA and non-compete, don't get bonuses in line with product sales (N% of sales go to my check), etc I am not aligned.

The only people "aligned" are the most useless. Sales. Yes, things need to be sold but if the people laboring are not incentivized sales will be useless along with the entire C-suite.

There is no such thing as a "sufficiently incentivized" laborer unless you're paying them a chunk of sales (see: a co-op). Hence why anti-work is such a popular concept even among the highest paid cohorts. Even as developers, we are being robbed blind and are worth far more than they pay. There's a simple test for this: if you work 20 more hours next week will your check potentially go up significantly? If not, your labor is being stolen from you.
