I've certainly decided that remote-working is worth a reasonable chunk of money in my salary when negotiating. It's not quite a must-have, but it's close.
It's more that I'll consider a lower offer from a remote-friendly company than I would from one which requires in-office work. It's worth money to me to not have to commute, essentially.
Actually making the offer to them of "I will take $X/year less if you let me work from home" wouldn't be smart, just because if they took it then it'd put me into a weird special-case category which wouldn't be at all good for my integration with their team.
