The Intuit are a relatively recent group that's developed incredibly sophisticated technologies and cultural traditions that specifically enable(d) them to live on the ice and even then they're only dealing with our temperate Holocene climate. Ancient people wouldn't have had the benefits of that advanced technology and their environment was far harsher than today. The high arctic was one of the last places on earth inhabited by humans. We don't find evidence of humans (archaic or modern) before about 45ka. Even then, habitation seems to have been minuscule outside refuge microclimates for millennia. Beringia was probably the biggest and most important of the Arctic microclimates, likely comparable to modern Alaska in some areas.
