Non-technical users might not be aware of much.

E.g. most peoples don't really think or ask that their tap water be free of cholera and other harmful substances, and yet we might want to make sure that continues to be the case. So it's not strong argument worth arguing about.

The real argument is - how much a compromise a replaceable vs non-replacable battery is. And I suspect the biggest part of non-replaceable batteries is actually superficial vanity considerations (gee, is it 7mm or 6.5mm), and planed obsolescence making more money. But the technical aspects are still a valid debate.
