That assumes you’re working in some kind of agency or consulting environment where you repeatedly produce similar or even distinct things. As opposed to a product company that has already produced and is humming along, which is when most people get hired.

Estimating the delivery of a product whose absence means zero product for the customer is very different. A company that’s already humming along can be slow on a feature and customers wouldn’t even know. A company that’s not already humming is still trying to persuade customers that they deserve to not die.

Not at all. This can work fine in product development, as long as you limit the level of technical risk. On the other hand, if you're doing something really novel and aren't certain that it can work at all then making estimates is pointless. You have to treat it like a research program with periodic checkpoints to decide whether to continue / stop / pivot.
