Sorry for the wall of text, but it is all I have to say. And sorry for english misspellings. I'm still learning 
Maybe my open play encounters with other commanders will help you understand some point of view. In my opinion this game is not about ganking at all.
1. Being ganked with zero words: I was ganked a lot of times. First three times I was just blow up to the sky without chance for fighting back and without any word from attacker.
2. Being ganked, with some words: I know you reading this, Commander

. So I was hauling cargo for Interstellar Initiative. I knew what will happen. One of the gankers, maybe PvPer, maybe not, wrote on local chat "I hate everyone!". So everyone should expect what will happen around

3. Being attacked for a role play reason: So I was hauling some other cargo for some other Interstellar Initiative. I hauled for the Empire. Other Commander was Federal agent. He interdict me and asked me: "Are hauling for the Empire?" I answered: "Yes". So he attacked me. This is a good exemple for me how PvP encounters should looks like. And that was fun. I menaged to escape him twice, but he hunted me for some time.
4. Fighting with Commanders who I like to call a True PvPers. Even if I'm not a PvPer I know some pure combatant Commanders who like to take fair fight. I'm just not a good opponent.
5. Honorable gankers, sometimes: Maybe somone will not belive me, but I know at least two honorable gankers. One of them, a well known ganker, he treated me honorably. I was close to loose my second encounter with him, so I retracted my hardpoints. He did the same thing and we left the fight. He's my in-game enemy now, but I respect him

6. Responding with fire: I'm roleplaying a loner so I'm not going to join any faction and any squadron. But I'm always standing on the good side.
-Fighting with gankers in hotspots like Deciat.
-Trying to protect commanders in Interstellar Initiative. I still remeber that hero who hauled cargo in T9 in open and always asked on local comms for assistance.
7. Helping commanders in their tasks:
-One of my favorite moments in ED was in Guardian ruins: I was there sitting on the ground and waiting for other commanders to arrive. And I've offered them help with shooting sentinels while they can focus on the task with blueprints.
-Vengance: One hour later a ganker has arrived, in his Corvette. I've send him o7, and he responded... with fire. I had a light ship with high range, but not so tough enough. I fought him. And I lost. So I decided to go back to Witch Head Nebula for my tougher ship. And I've done over 35 jumps back to guardian ruins with hope he will still be there. And he was. He killed another commander who also fought. So I cought a guy in Corvette without shields and with 16% of hull... And I made a revenge. For myself and for others.
8. Helping commanders attacked by pirates and gankers in mining hotspot in Borann.
9. Winging with people spotted for the first time over the Palin's old base to fight with Thargoids. That was another best experience in ED.
10. Deep engagement in player driven comunity goals. Like DSSA mission.
-That was absolutely great adventure. We have flew together far away, deep in the Galaxy. We minned together, explored together, have fun together for almost 2 months.
11. Winging with commanders hauling cargo. Sometimes you dying, sometimes they dying, but a least noone is dying alone
So there is a lot to do except ganking. There is a lot of reasons to shoot and have a fun with combat, avoiding troubles, escaping and pirating.
I don't like PvP in this state like we have in ED now. I don't like ganking only for ganking, without words, without any role play.
To summarize my point of wiev: I know there will be trouble, blockades, wars, pirates. I am aware of danger. I'm taking a risk and I'm trying to have some reason. I know that guy who interdicting me also should have a reason.
But I'm not understand 'no reasons', for lulz, for grief, for salt. And no, I do not understand that 'no reason, is a reason too'. It doesn't make sense to me.
