Do bloggers *have* to be relatable?

I love blogging. I love expressing my thoughts in a written way, and learning new skills and interacting on social media. But one of the things I love most is reading other people's blogs, and watching Youtube videos. But if I watched people constantly that reminded me of myself I'd be pretty done with the internet.
There has been a whole lot of chat in the last year or so about people's once-favourite bloggers becoming unrelatable as they switch from Primark hauls to chatting about their new Gucci purchase, or vlogging from their mansion rather than their old flat. The idea that become unrelatable makes your content worthless in terms of consumption has been bandied about, especially in the context of 'x' has more money now, and so they're not on my wavelength, so they're cancelled.
And I get it. It makes so much sense to surround yourself with content that you resonate with and that makes you sit back and think 'that's a bit of me'. It's fab to see other people's flaws and realise that you're not the only one that likes to indulge in beans on toast for dinner sometimes, or that manages to smash a highlight palette the first time you open it. It's refreshing to see that level of honesty and that little bit of something that you absolutely relate to.
But, bloggers don't *have* to be relatable, and I don't understand why there's such a pressure on us to be. I LOVE watching aspirational vloggers and reading blogs where I don't relate to the author. I love learning about things I can't relate to . For example, reading content about chronic illness or disabilities that you don't know anything about is not always going to be relatable, but it's sure important and worth getting into. 
One of my fave Youtube channels of all time is the SacconeJolys. And I can't relate. They're a couple with four kids, six dogs, and a hell of a lot more money than I could probably imagine and they vlog everyday. There are pretty much no parallels between my life and theirs. But watching their vlogs brightens up my day.
Branding someone as 'unrelatable' almost seems like a way to avoid thinking about the fact that maybe you've grown out of their content: maybe you wanted them to stay the same, and they didn't, but maybe you've changed and you're not quite ready for it. I see over and over again claims that Zoella's now unrelatable because of her wealth, but I think a big part of it is the fact that a lot of people have outgrown her. As teens we related to endless clothing hauls, makeup swatches and fun days with friends, but as adults we spend so much time consumed by financial pressures and time restrictions that the core of Zoe's videos are out of our reach. 
We can't restrict someone's own growth, whether it's due to a change in finances, or their outlook on the world. Yes, they might not be relatable to you anymore, but they don't have to be, and you don't have to consume the content they're putting out there. It's okay to 'abandon' a creator because you don't see eye to eye with them anymore, or hear anything that makes you think 'mmm that's a bit of me', and we shouldn't put a pressure on ourselves or anyone else to do so.
