“Selfish” would be a situation where sufficient community exists that cooperation is at all possible. I think most preppers will simply tell you that they are expecting and prepping for complete collapse. As in, like it or not, “every man for themselves” would come to them, not them seeking it out.
In other words, without arguing why a “every man for themselves” situation can’t or will never happen, the rest of your argument becomes irrelevant.
Now that question is fascinating. Haiti comes to mind as an example scenario. Are community-skills relevant in the face of roaming gangs and anarchy? I think that depends on how desperate these gangs are for immediate versus long term survival and planning. I’m also not sure Haiti is an exhaustive example of the types of societal collapse that are possible or likely.




I enjoyed the depth of this answer. That being said…
4 copies seems like a level of paranoia that is not practical for the average consumer.
3 is what I use, and I consider that an already more advanced use case.
2 is probably most practical for the average person.
Why do I say this? The cost of the backup solution needs to be less than the value of the data itself x the effort to recover the incrementally missing data x the value of your time x the chance of failure.
In my experience, very few people have data that is so valuable that they need such a very thorough backup solution. Honestly, a 2$ thumb drive can contain most of the data the average user would actually miss and can’t easily find again scouring online.
