For you (and me) they don't. But the average person buying a £1000 bike would expect it to be put together perfectly and on principle it should be as should any other brand new product.
And there are a good number of people who are actually interested in bikes who still take it to the bike shop to have the gears adjusted, punctures fixed etc,.
Some people just can't be bothered to even learn the basics.
