It's not at all beside the point for those who chose to buy the game because other players cannot force PvP on them.
Unwanted PvP is just that unwanted. As the attacker is under no obligation to offer the target an enjoyable experience, neither is the target under any obligation not to menu exit and block the attacker. All three elements are part of Open play.
If something is not fun then players tend not to do it, and being targeted for unwanted PvP is clearly in the not-fun category for some players.
There seems to be some idea that players should not be able to opt out of itsiPvP, or that those who enjoy PvP should be able to force their gameplay choices on other players.
Put differently, some players don't like to be forced to interact with other players, by those other players.
Again, how is this any different if you replace 'PvP' with anything else?
I was referring to the ur-issue that PvP players want PvE players to engage in PvP with them, which never, ever works.
I don't think most of those advocating Open-only anything want PvP intolerant players to engage in PvP with them. I think they want PvP to be a viable means of engaging with the gameplay they prefer, without it automatically being a handicap. The implications of any system that actually enabled this would be to exclude those PvP intolerant players, but again, I'm not sure why PvP intolerance is something that needs to be catered to more than insertanythinghere-intolerance.
Unless your problem is that you think only your way to engage in PP is the correct one and no one should be allowed to do it any other way, which, well, sounds like a you problem.
PvP is actually my only way to engage in PP, because my CMDR will not pledge to any Power.
My CMDR has plenty of contextual reason to actively dislike every Power, though some are more offensive than others. PP also has a significant impact on the setting my CMDR exists within and is subject to, but without signing up for a faction, one cannot contribute merits. So, the only agency I have is inflicting some degree of attrition by attacking the odd PP CMDR when the opportunity presents itself.
I'm not an Open only advocate. I don't think such a system can work without numerous pre-requisites that are beyond FDev's current will and ability to implement, but I would definitely appreciate the ability to oppose Powers without having to have my CMDR enlist. I also understand the desire for the ability to directly engage one's foes on one's own terms, rather than being forced to engage in monotonous bucket filling contests to be effective.
All modes being valid for all areas of gameplay is not going to stop happening now.
Stop happening? It's never happened. You just gave an example of where Open was a decidly less valid mode for CGs in your previous post.
The modes are not and cannot be wholly equal by the very nature of what they are. Exclude certain interactions and the scope of gamplay that's possible changes.
Even if we ignore the intrinsic nature of the modes themselves, there is still precident for FDev specifically incentivising one mode over the others. You've been around long enough to recall the 'Race to Elite' and the win an NVIDIA Titan Black contests...both of which were required to have been done in Open. Not saying either of these contests were good things or something to repeat, but they are overt examples of Frontier trying to push one mode over the others.
