Yes, you're quite right. If she can make a go of it, that's great.
But I think she'll find, just like being a creator, podcaster or producer, it's harder than it looks.
Gwyneth, for instance, has a lot of earned money, comes from money, and is married to a very successful producer, having divorced one of the most successful rock musicians on the planet. Goop doesn't actually need to make money. I believe that statements of Goop's worth are wildly overestimated.
Martha Stewart took years of professional effort and ability to build up her brand. Mind you, she then went to prison for not paying her taxes...
On the back of her celebrity, Blake Lively started Preserve, a wholesome website/lifestyle portal shop that seems similar to what Meghan is planning. And it tanked. She closed it a few months later.
You need a lot more than a winning smile and some beige Montecito accessories to make a go of this sort of thing.
I will be interested to see her Netflix cooking show, if reports of that are accurate. Maybe she does need to let the public see her when she's not complaining on screen about the royal family.
