Should werewolves get married?

According to the accepted answer to this question on the benefits of marriage, if I were to get married I would get

• a piece of food once a day (if I remember to ask for it),
• a bit of cash once a day (if I remember to ask for it), and
• some lovin' to give me a rest bonus (if I can stay awake long enough after a tiring day of adventuring).

Now, I am a Level 30+ werewolf. Which means that

• I rarely eat food I haven't killed myself.
• I have tons of cash, like most players at this stage, so 100 per day is negligible.
• I. Am. A. Werewolf. No resting bonus. Not even Lover's Comfort, according to the wiki.

Even if I were much lower-level, food doesn't seem very useful in the game and the amount of cash you get is quite small. Does my...hairy condition effectively negate the only real advantages to marriage?

Yes, for you it'd mostly be for role playing purposes. There is one exploit that may or may not be beneficial to you depending on how much you need money. As that 100 septims stack, you can sleep for 24 hours 10 times for example and get a 1000 gold. This was slightly helpful for me when I was trying to buy loads of Master spells at 3000 each.

Apart from that its pretty much useless gaming wise especially if you do not need money.

Accepted answer, simply not so. Usefulness of marriage also goes in to who you marry. The blacksmith in Riften for example. If you're trying to get good prices at an smith(on ebony ore without having to mine it for example) this helps.
