Well, they certainly are common on web images, so one who is a 
predisposed to dislike digital images might be excused for thinking them 
to almost be an (un)natural part of digitally produced images. Seeing 
only 8 bit, highly reduced and compressed images on the web  is 
certainly not a great way to be able to judge the quality of images.

Sharpening and compression artifacts aren't a necessary part of images 
from digital cameras. And those from most DSLRs at reasonable isos, in 
RAW images or JPEGs of modest compression and with reasonable internal 
sharpening settings are remarkably smooth. Free, in fact, from the 
artifact* of grain so familiar to us from film that we take it for 
granted, and even sometimes as an asset.

More sophisticated sharpening can avoid the particularly annoying halo 
effect.

* a part of the image which was not visible in the subject and which is 
a result of the process of creating the image.
