That's two more clicks than zero and one extra device that you need to bring. I get it, you'd never leave the house without your phone, but sometimes I don't want to have my phone and all of its notifications following me around. If I don't have my phone and I don't log into Instagram on my laptop, I don't get distracted by it. Being able to go further without having to be tethered to wifi is freeing, albeit for a rather specific digital slice of freeing.
