How to translate the phrase 利而物利章 in context?
after reading other literary chinese texts, here's my approach :)

君道何如 - what is the principle(s) of sovereign

利而物利章 - this verse is very tricky, i would interpret it as "利而物利" + "章"

the first "利" is shortcut of "利民", beneficial to people

而 - and

物 --> 勿 - not

the second "利" is shortcut of "自利", beneficial to oneself

章 --> 彰 - 明顯 distinct, obvious

together, 君道何如﹒利而物利章 is roughly:

what is the principle(s) of sovereign (君道何如)? [he should make it] obvious (章) that [his acts are] beneficial to people (利), and (而), not to himself (物利)

ludi kun, in volume 1 of 呂氏春秋, chapter 4 "貴公", there's a verse

"利而勿利也", with a remark "務在利民，勿自利也"

edited, info added.

it's very common in literatures of yore, 章 is used, in lieu of 彰. even in 呂氏春秋, there're several usages:

孟春紀﹒本生: "萬物章章"
