This reads like someone which had bad management using effort estimates as hours and bugged the team about it. I'm saying that having seen plenty of environments where they do Scrum wrong.

> Because there are no sprints, you don’t have to worry about whether something fits into a sprint

I like fitting things into sprints. It forces tasks to be broken down into manageable items. If it's too big to fit, it's also probably ill-defined. Sometimes it goes over the sprint; it's alright; discuss during retro and learn from it.

> If an emergency arises, everyone pauses their work

You can still do that with Scrum. Scrum is a framework to estimate the effort and measure at fixed points in time. That's not an excuse to dismiss issues. Unless all of your work is unplanned, you can handle surprises AND estimate your leftover velocity.
