> While you plan a sprint, you loosely plan an increment and using the estimates and velocity, project where you will land.

That sentence contains four verbs: plan, plan, estimate, and project. If your sprint were a single week, planning two things, estimating all the things, and "projecting" the sum of all the foregoing adds up to... Quite a lot.

You'll spend a large portion of your time doing these... fundamentally non-agile things.

Scrum is basically Waterfall, packaged as a lot of mini-waterfalls and sold as "non-Waterfall".

You can't run a marathon as an endless bunch of sprints; a marathon is fundamentally different from a sprint.
