Anarchic idea of suited office worker, ignoring page weight for Americans (8,2,5)

'americans' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'anarchic idea of suited office worker ignoring page weight' is the wordplay.
I cannot quite understand how this works, but
'idea' could be 'property' (property is a kind of idea) and 'property' is present in the answer.
'weight' could be 'heft' (heft is a kind of weight) and 'heft' is located in the answer.
The remaining letters 'ist' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

'for' is the link.
