I don't see it as "hardcore" argument - it's just RNG can be frustrating. And while some players want to be able to reload when that happens, I like to be forced to deal with it. When XCOM kills my favourite unit, be it through RNG or my stupid mistake, it is tempting to reload. It is very tempting to reload when my rogue specilizing in lockpicking rolls 2 and fails to open the chest.
If I get that frustrated I just throw my PC out the window or sulk about it for months. Admittedly the former hasn't quite happened yet (though I think I did once throw a mouse across the room; ISTR it was the end of Act 1 of the Witcher when I was absolutely unprepared for it, so not really the mouse's fault, but it was a horrid mouse anyway) but I have often gone on a sulking spree. About three months for Morrowind after first getting pwned in that cave outside Seyda Neen and the indignity being multiplied by the same thing happening with one of the Thelas Sisters and her rats. I'd taken it personally and not realised I'd experienced my first "oh, that's just what Morrowind does" moment. And then there was Bioshock Infinite and its checkpoint-only saves which took at least six months of sulking.
I suppose I did a similar thing with the "prevention" approach by installing a mod on Oblivion that prevented fast travel (and others which had actually dark nights and mandated getting enough sleep etc) which IMHO paced the game much better compared to my former "action and adventure all hours of the day and night" playing style. I eventually uninstalled it as some quests were too annoying to repeatedly traipse across Cyrodiil and back just to deliver a message and nonsense like that but by that time I'd trained myself to just sauntering around rather than using fast-travel points.
