Well, I like them because it makes it feel like a real house with problems a house in the woods would have.
Granted, a little bit of adrenaline like this makes it more like a real house in the woods, and inhabitants of such a real house would take some measures to minimise such attacks. This is why a number of posters who feel differently than you provided quite a few ideas for ingame features which would allow them to get rid of what they see as an issue - I'm not going to repeat them all here.
But all that has already been said before and in the meantime, another thing occurred to me. Some players, count me among them, I guess, see their ingame house - be it in the city or in in the wilderness - as a sort of safe haven. Others may like the idea of "there's no place safe", but really, there are also players who would like to have a fair certainty that having spent some time slaying draugr and so on, once they get to point X, nothing unexpected will happen. I think this is why quite a few people are complaining about skeever infestation even though it takes "literally two seconds" to kill them.
And this is why I'm still supporting the idea of being able to buy optional features to get rid of or minimise the nuisance. Besides, a guardhouse and painted stones would look cool outside the house ^^
