I haven't watched the video you linked because Maxtech is a terrible source of information, but I assume it boils down to 16GB being better than 8GB. No one is disputing that. If you buy a machine that's underspecced for your needs, you made a mistake. If you buy a 32GB machine when you need 64GB, you'll face similar issues, but that doesn't mean no one could possibly get by with 32GB, it just means you bought the wrong computer.
What people are willing to pay for something doesn't always come down to $/Gb of RAM or storage. If you're not happy with this config, just don't buy it. No one is forcing you to. Buy a specced up Pro or Max config. Buy an M2 Air. Hell, buy an M1 Air. Look at your budget and figure out what your actual needs are and buy a computer that meets those criteria. Why complain so much about a machine you clearly never intended to buy in the first place?
