What kind of user do you imagine that has the combination of a need for running many large, memory hungry apps at once but doesn’t know enough to consider how much RAM they might need? Your basic: browsing, email, word processing, photo editing user will be fine with 8GB of RAM and is unlikely to run into performance issues.
All you have to do is be a user who likes to keep open a lot of web browser tabs (there are a lot of us in this category, and for all sorts of genuine, useful reasons, so don't scoff at the idea) to find the AS machines choke up with only 8GB RAM.
I have a good friend who bought one of the first release M1 MBA's when they came out, and being the typical user you described, happily picked up the 8 GB machine. He also had simultaneously found a buyer for his old laptop, so didn't have it to fall back on. And even with the 2 week return warranty period, the 16 GB versions were still being produced, so weren't even available for sale, so he was up sh*t creek without a paddle.
Yeah, he prefers Chrome, and yeah, he tried switching to Safari instead, but he said it actually made things worse!
He suffered with it, and wasn't willing to lose so much money selling it 2nd hand and buying a new 16 GB model. Until I reported to him that I was loving my 16" M1P MBP (with 32 GB RAM), so he bit the bullet, and upgraded to a 14" MBP with 16 GB RAM. Finally, he was happy, but what an unnecessary drama. Especially when you know how damn miniscule an amount of money it actually costs Apple for the RAM that goes into these machines. In reality, the only reason the base amount isn't simply 16 GB, or even 32 GB, is purely so Apple can ream the buyers for upgrades.
