Yes, but Scotland is the only country in the world for which that is the case.

Legal protection is vague at best in any country other than the two you cite.

Arms were not granted ANYWHERE IN THE WORLD until the 15th century (hardly 1500 years ago) and the original purpose of "granting" arms (in England at least) had everything to do with collecting taxes and exerting control over the feudal system. No more. No less. It was never about recognizing one's merits or social standing.

In some countries, in fact most on the continent of Europe, there was NEVER an official heraldic authority.

If this is the case, I honestly wouldn't bother registering them with anyone unless you're interested in getting in touch with others that have assumed arms.
Unless you live in Scotland or South Africa, you have no recourse if someone else uses your arms regardless of whether or not they are granted or assumed. I don't buy into the "traditions of your ancestors" bit. The reason to have a grant from Lyon for a Scot is because they have to, plain and simple. That isn't a tradition, it's the law. Like any number of other things, that burden was lifted when emigration occurred.

But why on Earth would you want a registration from a country with which you have no connection whatsoever? If it is simply so that you can have the seal of approval from a government entity, then I would suggest your self-worth deserves some introspection.

That is simply not true and a very Anglo-centric perspective. The assumption of arms is and always has been the norm on the continent of Europe. Nothing about a grant of arms makes them more real in any substantive way to anyone except those who live in countries where there is an acting granting authority. While a grant to someone living outwith Scotland may be more meaningful to it's recipient, granted arms are in no way, legally, socially, or otherwise better than assumed arms.

Yes, anyone with a bit of effort and the requisite cash on hand. Given that all it takes is the ability to pay for a grant of arms to "achieve" one, it makes one wonder who is the real social wannabe, doesn't it? There is no background check for obtaining a coat of arms from any of the authorities and they are reactive rather than proactive grants. Therefore, they do not convey any type of social status.

In this instance one might find oneself being ordered to remove the arms or face prosecution.
I am quite aware of the laws in Scotland regarding heraldry. If one moves to Scotland, that puts them under the jurisdiction of Lyon and that is a game-changer. The law of the land is the law of the land. But I doubt what you're saying applies to everyone with assumed arms. I'd be willing to bet Lyon would recognize the arms assumed by (then Mr.) Daniel Westling.
