Slippery slope is a fallacy...you are talking about fictions that create fear to sell a point...not discussing the facts of the point. Although there are plenty of people that desire a way to carve up space assets into 'King of the Hill' type gameplay...the devs...and David himself have stated quite clearly that 'control' will never occur. In other words, just like the modes, those opinions do not matter. Those folks need to accept that...and start coming up with ideas that can be worked with within the framework of the game.
There are many tools that can be added to make this game a lot more comfortable and easy to deal with managing groups of people...which, definitely appear to be scheduled for addition.
It's not a fiction that there are player groups who want guild play along similar, if not identical, lines to Eve and similar games, a point you've acknowledged yourself here. Which is why I deliberately used 'IF' - if Frontier decides to go down that path. The definition of fallacy is 'mistaken belief' - it is not mistaken to believe that IF Frontier ever did decide to go down that path that it would be a negative impact on a very large portion of the playerbase (a majority, i would argue). It remains to be seen whether it is a mistaken belief that Frontier won't ever go down that path - I agree it's unlikely given the stance to date, but is that reason not to continue arguing against it when someone proposes it? I agree that improved tools for good group coordination would be great. It also remains to be seen whether it is a mistaken belief that introducing such tools wouldn't lead to more guild-focused mechanics such as asset and territory ownership (which is the bit I think most are concerned about because of the implications). The more nefarious groups won't want it to stop at 'improved tools' - that's not a fallacy. While I also agree that Frontier currently as no plans to go down that path and that such groups need to accept that, while such groups keep agitating for it, I will continue to argue against it. It's part of keeping Frontier mindful that many of us don't want it. If nothing else, continued threads like this empasise for Frontier that it remains a highly contentious matter, which in turn reinforces that they have to be very careful in considering what they do or don't implement for guilds/clans - which at the end of the day is all I want them to be......careful about what they implement.
