Well its a good idea to create MS account to login as MS is starting to integrate the Store & Cortana more into Windows 10. Plus with the new Anniversary Update your Digital entitlement data is linked to you MS account which will make it easier to do a clean install if you change hardware. Meaning it will activate without having to call Microsoft.
If you value even a shred of your privacy, you will not follow this advice!!! Go ahead and create a MS Account; there are several worthwhile things you can do with it via a browser (and not even, necessarily, one of Microsoft's). But *do not* log in to your PC with a Microsoft Account - that triggers all of the most intrusive "telemetry". Of course, if you can't live without Cortana talking at you and pitching various things for you to buy, go ahead, but do it with your eyes open. Sorry, I prefer to choose when and how I interact with MS rather than letting them do it whenever and however they feel like.
As far as the "digital entitlement" goes, that has no connection with the Microsoft Account. The entitlement works fine whether or not you log in with MS Account. Yes, with the account login active, you can sync other settings, but I change my mind about settings from time to time anyway so that doesn't really matter for me. Also, many of the settings I've done are in group policy or the registry, which the "settings sync" doesn't save. So again, no need to log in with a Microsoft Account to save your system.
Besides, when syncing various things online you 1) use network bandwidth, which isn't free or (for many of us) fast, and in the U.S. at least usually has some monthly cap designed to make extra income for the ISP; and 2) use Onedrive which has a low cap for "free" storage (around 5GB now, I think) - good mainly for small stuff and temporary, closely managed material. If you want to back up your system, do it the right way to an external hard disk or similar appliance.
