Tyrrhia: Does you accessing GOG (more specifically, your GOG library) run without an account? Nope.
Does the GOG Downloader run without an account? I've never used it but I don't think it does, either, because it would totally break the purpose of the store—so, nope.
Galaxy is pretty much the same thing as the two methods mentioned above, except that it's also used for conveniently downloading, installing, and launching your games (and browsing the GOG site if you so desire, but better leave that to traditional browsers) without doing it all by yourself.
Pheace: If this were true people would have no issue with Steam. Does the GOG Downloader run without an account? I've never used it but I don't think it does, either, because it would totally break the purpose of the store—so, nope.

The difference is that you only need to do the two examples you gave twice, and only to download your game, while for Galaxy MP you need to be logged in every time to make use of a part of your game (for those that use it)
(unless you were only talking about using it as a downloader, in which case my bad)
The only restrictive thing concerning Galaxy (except for the lack of some platforms support and stuff like that) is that for some games, you have to use it in order to play their multi-player. I don't know if what you download and install via the installer packages is the same thing as what Galaxy does, so I don't know if you could download Shadow Warrior 2 via the website, install it manually, and launch it via Galaxy to access its multi-player; but if GOG were to include some Galaxy components in installers to allow for multi-player account stuff without requiring Galaxy to be installed as some users seem to request, they wouldn't be any less DRM-ish than Galaxy, either (not saying they would or wouldn't be DRM as it depends on your definition of the term, but it would basically be the same).
Anyway, one thing that always amazes me if that some people apparently think that Galaxy is DRM just because it's another application they have to download. First, they don't seem to realise that the GOG Downloader and their browser also are applications; and second, they would be OK with a "Galaxy-lite" version just because it wouldn't install another application on their system—that would be stealthy. To better illustrate the foolishness of it all: it's like if shepherds weren't allowed to enter their fields alongside their sheep, but would be perfectly fine to enter them if they were hanging from the belly of one of their sheep. :P
