I am glad we have come to agree in everything.
Our difference here is only a semantic one: I wouldn't say you are chopping with bonus, I would say you are producing the Mandir as early as possible so you save your trees for it. You would do the same if you didn't have accesss to the bonus resource.
Yes. I wanted to keep my example easy and clear. Having bureaucracy or OR or a forge has no impact on the decision to chop with or without the 100% resource bonus (or with or without the 25% buildings bonus as in your missionary-monastery example).
However, if I have nothing better to build than the monastery for 2 turns and want to switch to a Hindu Mandir as soon as copper is hooked up then plainly I'd be better off chopping with bonus to get the Hindu Mandir completed in 18 turns with the monastery completing after a further 6 turns.

It would appear that your argument applies to units or buildings when running OR. For example if you plan to build a missionary and a monastery it's absolutely fine to chop the missionary? Do you agree?
