...why?

We'd still have modern computers and stuff. Dropping productivity wouldn't revert technology itself. So if you ask people "Do you want the same amount of housing and clothes and cars and services you could get back in 1994, but while working 4 days a week instead of 5?" what's the horrifying factor that makes them say no?

Real GDP per capita has gone from 41k to 67k, so going back to 1994 could actually be done with a 3 day work week.

Most people wouldn't want to because they would have to cut 40% of their spending across the board.

there are a lot of people today that can already have the option to work less for less money but dont choose to do it.

Okay. Well "they would decline" is pretty far from fighting tooth and nail.

No, they have declined. Already, and continue to do so.

People like to have more stuff, bigger houses, better cars, air conditioning, whatever.

This whole thing could be brought about by a law banning work over 3 days a week.

I think people would fight tooth and nail.
