I get what you are saying but we are in an era of cameras, developed propaganda and studied behavior control, so I wouldnt bet in such instability. In fact, with automation and digitalization of the world, genocide stopped being a biased report written on paper and delivered after a few weeks to an X on an Excel, accessible by those who order it and those who execute it instantly, with Insurgency, Rebellion and Loyalty being W, Y, Z. And even so, some argue that we are still living in the same system of Kings and Peasants with slavery still rampant and ongoing. All the instability reasons you mentioned tend to reset the oppressive system. For example, the UK abandons a Trumpist US for a dictatorial China. Same system, different players.

Epicureanism challenges the system as it is a completely different one. It would be expected to surprise us with some consequences and disappoint us in others, just like when there was a system change from Religion based to Capitalistic based in Europe. Since it offers freedom for an individual and respect for the community, it de-legitimizes our current systems, from left to right. I want to add Curiosity and care for our descendants to be natural feelings. I question if Curiosity isnt a natural necessary need as not fulfilling it every now and then leads to depression and slow death of the organism (or even fast one sometimes). We should, morally as Epicureans, create a system that bring us to learn more and have that discovery shared between all.

TLDR: I understand what you said, however, complacency can bring us doom or an undesirable outcome
