avocados that post is bullshit tbf. Natural living is actually one of the cheapest ways to live so how they are finding it expensive I have no Idea.
All the usual 'natural living' ideas cost very little. Esp if you follow a zero/low waste/ low impact lifestyle. I know because I do it myself.
Yes, housing and fixed bills - council tax etc are expensive but saving money on fuel, water, food are all part of natural living ethos
If she's only shopping in healthfood stores then yes, her bills will be silly high. I know vegans and natural living advocates who spend an absolute fortune on health supplements, super foods, fancy ingredients that are meant to have cosmic powers
When the truth is you can eat well, naturally, vegan, gluten free or whatever your diet is very cheaply.
It looks like she has bought into the Woo of the supplements and healthfoods and that's why its so expensive and it doesn't need to be.
Hell with a small garden a lot of the herbs she uses she could probably dry her own stores and the homeopathy. Surely dipping a leaf in a big jug of water will suffice? 
Its interesting that their careers are very much of the moment and could disappear quite rapidly :/
