This is so much wrongs here. Lets start with the I do not like gankers. but your suggested measures are basically against the TOS that you agreed too, and you are basiclly doing what you accuse the other players of doing, pushing their gameplay onto you, now you are trying to push your wanted gameplay onto them!
I have a hard time believing that every single time you have tried open, someone have killed you. I have done hundreds of hours in Open, including visiting founders worlds, engineers, and I have been killed ONE time by a ganker, and got interdicted twice... Now there might be a few differences between where and how you and I play, I do not have my home base in founders world or in the same systems as engineers, ie any of the hotspots for gankers to be lurking around. My friend found a nice system in the bubble, that sold the ships and modules we mostly needed when we started out, so that became our system. We know that many players travel through our home system, as we can see in the station log over visits.
Then there are SEVERAL options available in the game for you to use to define how you want to play.
* Game modes: Solo, Private Group and Open
Your choice, and there are Mobious where many like minded players can be found, ie, I want to play and see other players, without having to pew-pew at eachother.
Choosing game mode for the appropriate activity is give choice... doo you think gankers do all their engineering, collecting mats etc, in their gank ships in Open? No, they chose Solo/PG to do these sorts of things, so they do not risk to run into a fight they cannot win! I have followed the ganker who killed me.. I sent a friend request and he accepted, and he was very mich confused and upset that I did NOT spew alot of garbage in their direction.... but it allowed me to follow the movements, and game mode... and only time I spotted the ganker in open, it was in a hotspot for killing other players, all other times, the ganker was in solo!
* Blocking, you find a player doing something you do not like, for example, killing you, block them and you are very unlikely to encounter them again. This is your main tool to opt out of other players idea of what this game is about. But it is not an option for you to tell other players how to play!
* Play style and a general be ready approach. What was you doing when getting killed, what ship did you fly etc, this is not about you being a bad player, it is about awareness about your surroundings and what you can do to protect yourself more. Do you care about seeing any hollow squares on the radar? Do follow what the hollow radars symbols are doing? ie, are they moving to get behind you? etc, IF you do not bother or know about this, then just blazing your way to the destination the shortest route on suppercruise assist and "watching netflix" is recipe for disaster when playing in open. So being aware about your surroundings allows you to be more prepared and also avoid some situations. For example, if I fly in open to a hot spot, I take the LONG route to the destionation, as most of the gankers sit in the middle between the star and destionation to catch you when fly past them. if I fly in a big circle to arrive at the destination from the other direction, there is no time for them to be able to get behind me and interdict me.... and I do not loose that much time doing this!
Stations, do you speed near a station or not? playing in solo, the risk of speeding is mostly non existent. ie, you get a reckles flying fine for bumbing into things, and you are very unlikely to destroy another ship. Add players into the mix, and now I can suicide into your speedinig ship with a weak sidewinder... I go kaboom, you get "rewarded" for killing me, as you survived the crash, so it must have been your fault or something, so the station sets out to punish you for killing me... unfair yes, but the rules are the same for everyone, solution is siimply, do not speed, what now happens is that I kill myself, and station just logs that you where not speeding, so you did nothing wrong and are free to go unharmed.
So use the EXISTING tools of the game to play the game how you like, and exclude those players that have a negative influence on your experience. But you also need to consider your own playstyle, as NPC's are predictable, players are not. and if you want to play with other players, you most likely have to adapt to this.
