This was why when Argentina swapped out a job guarantee (plan jefes) with a UBI-type program, many of the women who did the job guarantee jobs of caring for the elderly, etc. kept doing the work in spite of the government telling them it wasn't "necessary" any more.

While it's theoretically possible that they might have spontaneously started doing these jobs if a UBI program had been initiated I'm not aware of any example where this has happened.

Yes. Many types of extremely valuable work in our society is not valued by the market and so is not compensated.

Caring for the elderly, caring for children, my elderly neighbour who sometimes picks up trash on the street, etc.

There are all kinds of crucial work our society desperately needs done, but which are often not even conceptualized as work because there's no wage attached to it.

Also, commercialization can create fake economic growth.

For example, suppose in the past one spouse worked a job for a wage/salary and the other spouse cared for some of the couple's ailing parents, provided childcare, and cooked for the couple's children and parents. Now instead, the second spouse also works a wage job, both spouses pay higher taxes some of which go to caring for the old people, and with the extra income they instead purchase prepared food and pay for daycare. The economy grew a lot because formally unpaid labor is now being paid for, but is everyone better off?

Note: I don't think women should be limited to being homemakers, this is just an example.
