Have you ever played a game, which was not a video game, where you had to start over, because you made a mistake within the rules of the game?
This punishment for a stray shot is inadequate, especially within the margin of the other consequences in this game. Also, as others mentioned, this situation can happen under different circumstances, without a player fitting the tiniest FSD possible.
To those who say it is OP´s fault: What would the game loop look like in detail, if you want to play in a ship with low FSD range? To prevent yourself from being stranded, before you transport your ship into a system, you´d have to check surrounding systems for being reachable manually(!) and if stations with the right factions are present. That is ridiculous.
The new C&P system is so complex, that the Lead Designer Sandro answered a question regarding C&P starting his answer with "I believe it is like this". I think it is too complex and not transparent enough (even to long term players). Of course in-game explanations could help, but again they don't do that around here.
