There is a spectrum where the emphasis is on the team vs the individual and I am very deliberately saying that a point closer toward team is generally more effective.

Autonomy is not "do what you feel like" (https://jchyip.medium.com/is-your-autonomy-strong-or-weak-885aef97fcbb) is another way of saying this.

I agree a person is not their team. Not every team is a fit for every person. It is useful to accommodate for real people when designing teams. A single person unilaterally imposing their work style on the entire team is worse than individuals adapting OR joining a different team. The agency is the ability to sign-up or not.

Product development, like certain team sports, is more about team flow than individual flow.

Flow in either sports or programming has nothing to do with adrenaline. See The Rise of Superman by Steven Kotler.
