I'm not trying to be facetious - you seriously can't provide your own meals and snacks working from home?
>> Many people who work at these companies live in big cities where they don't have huge amounts of space and it's not conducive to being productivity, particularly if you live with other people, if you can't get some form of separation.
Do you live in that space because it's close to your office? Ok, so now you're remote you can live anywhere. If there was no pandemic you could work from a library, or café or dozens of other places. You could move around each day. Or you could move to a cheaper location and have a nice home office.
