Good luck convincing most people to wear t-shirts and jeans every day, let alone a small number of them. No thanks.
You know some people have occupations where you get really dirty, right?
You know some people have to "dress to impress" for work, right?
Not everyone can move to "simple" clothes so easily, including most people who are employed.
And... none of the people you mentioned are likely to benefit from the first several waves of robots cleaning outfits. Which was what I had on my mind.
That is, if you are a person that feels they need help cleaning their clothes, you are likely not a person that will benefit from the first robotic solutions. Unless, of course, you could already benefit from the current outsourcing techniques for the job. And it will be a while before those are beaten in price.
I say this as someone that has grown to love our robotic vacuum. Things is awesome. Probably still cheaper and more effective to just sweep and vacuum manually.
Similarly, eating out comes close to solving the first problem. Will be very cost competitive with robots for the same in the foreseeable future.
To the point that solving this problem will require more behavior change from us than we're likely to realize.
