People try all the time, and they die all the time. Harry fought like 20 players outside of a station and killed like 10 before he just went and docked. Kimob fought a wing solo and killed them all. I've fought 4v1, 3v1, 2v1, and killed all of them or forced wakes. If you are at all competent in this game, you will not die unless you choose to, and unless you're an active PvPer, you have literally no chance at killing one of us.
By 'die' you mean eject, of course. No actual killing of CMDRs ever occurs. Think of the outrage that would cause, given how severe losing 5% of the value of one's ship is often considered...
But, yes, the point stands. Most competent pilots rarely lose ships. Even competent pilots who are inclined to protect incompetent pilots from other competent pilots often cannot do so...the weaker pilot is often shot down and the aggressor escapes before the would be protector can do much about it. There are occasionally exceptions, but they are rare enough to be exceptions.
This is a fundamental property/flaw in way
Elite: Dangerous handles instancing and encounter distance. There is little time to react and attrition is only rarely a factor. There is really no way around this and, most of the ease of use/convenience suggestions that have been implemented, or that I hear calls for, will only exacerbate these issues.
But if I have to hang out with Triadius or SDC or The Wild Boys to skill up -
You don't need to hang out with anyone. It's perfectly possible to learn the ropes on your own...well, not entirely on your own, but against enemies rather than with friends.
