My first thought was that if your time and effort really is so valuable that it economically makes sense to use a service like this one, then you probably can afford and should have a real concierge/personal assistant. It seems to me this hinges on an emotional (i.e. economically irrational) need of (upper?) middle class people to feel rich and too “important”. Which is actually not a bad business model at all, tapping into people's feelings. It's actually one of the best things to base a business on. But I could be wrong. Maybe there's a sweet spot in the price-utility ratio where this makes sense for people who are not technically rich and busy maintaining the wealth. It's interesting.
