You are aware that Google apps are proprietary and subject to legal clauses imposed by Google, right? What you are asking for here is just illegal. Even if it wasn’t, and a user could install GMS legally, after that they would install their banking app or some comercial game and BOOM, SafetyNet wouldn’t allow them to use it because they are rooted. Android ecosystem is controlled by Google and that’s a fact, with and without GMS. But don’t worry: the Fairphone 2 bootloader comes unlocked unlike the majority of the smart devices, so of course you can install a custom recovery like TWRP right after you unpack it and treat it like whatever you personally and subjectively consider it.
See above? I’ve not needed to be unrespectful nor insult you through your arguments only to refute them.
For the other parts of your post, I agree with @BertG and @AnotherElk.
