I partially agree with the spirit of your comment, but I disagree that this doesn't solve real problems. If you think critically about all the little innovations out there that add convenience, it adds up to a lot more leisure time. I'm sure people thought car washes were decadent at one point.
For better or for worse, modern Western life is built on a thousand now-invisible time-saving innovations. I think we're at a transitional time in our culture. All this leisure time has historically mostly served to allow us to fill up our lives with increased complexity, but I think we've hit the point where that no longer scales, because it's simply too much to track. What Magic gets right, in my mind, is that it's part of a trend of abstracting away that new complexity. It gives you a single entry point through which to leverage a bunch of innovations that you don't even have to know about.
Where I think services like this can really win is if they can use economy of scale to improve upon the individual's own ability to optimize value for cost. This is possible, if say, they maintain a knowledge base of the best deals.
