The thing about Scrum is the observations and principles make sense, but then to sell it as a course they've turned it into very specific prescriptions.
I went on a scrum course and the takeaway was basically that feedback is a big deal, and you should try to get some repeatedly and quickly. It's also common sense that you should have tasks written down somewhere, and that some of them are more important than others.
You certainly need to think about how long tasks will take, but there's no reason why you need to do planning poker, that just seems to be one among many ways to think about how long something might take. Tracking velocity is another one of these things that seems replaceable.
If you have a team of people that more or less adheres to a few principles, there's no reason you can't get things done.
