I think when you can't find joy in your life through any other ways, like Eleanor Florence, shopping gets you there, even temporarily.
Let's see if we can compile a list of things Elle likes:
1. Spending other people's money or having things paid for her by others (Ginette, Joe, Chris, etc.)
2. Shopping: Nordstrom, consignment sites, Sephora, the list goes on
3. Dining and vacationing in the same spots in Hawaii
4. Cucking good pasta
5. Heavy makeup, post-drybar hair, and extensive plastic surgery/botox/fillers
Basically 4/5 of this list is tied to spending money (often at the expense of others or after scamming her subscribers) and cucking good pasta also takes up time and she needs to purchase ingredients...plus, how much cheese and pasta can one person eat???
I don't buy her new "hiking" addiction, particularly given that she only started hiking after people here mentioned how wealthy tech guys in Seattle are often outdoorsy and love to hike (she's proven again and again that she reads here REGULARLY). The fact that she wore loafers and strategically posed in a way to look thinner/more attractive in her "hiking" photo makes me think that she went there mostly for the photo op, probably to take a new pic to put on her online dating profile.
