I think I see Meyer's point, but I see it from a different perspective: 
classes do not only keep methods and their data together, they also 
categorize methods. This is important for two things:
- reading source: when a class function is invoked I know where to find it. 
But everytime I see a non-class function that i don't know yet, I need to 
grep through the sources to find it, because it is not obvious where to find 
its code. To fix it people sometimes use prefixes that can help you to find 
the right header, but this also decreases readability and forces you to 
invent new naming conventions (and as optimization was the original topic: 
long function prefixes also hurt linking performance when gcc on Linux is 
used)
- in public APIs: when I search for a feature in a large library I search for 
classes and then look at their methods. But when there are also class-less 
functions that could offer the feature I look for, I either need to look at 
two places (the class list and the function list) or the overview needs 
another level in the hierarchy to group closely related classes and 
functions. Both make it much more difficult to find a feature
