I’d say it’s not reasonable.

Yes, there’s the perception bias that makes absolute evolutionary sense when you deal with the ‘lion or stone’ problem.

However we as species dominate the planet because we cooperate. Religions, national states etc. are all imaginary sets of rules to ensure even more efficient cooperation in large groups. And here’s the problem: If you meet a new person with distrust he/she becomes more likely to actually act according to your expectation. Given that premise is true an individual distrusting each an everyone weakens its evolutionary fitness as it misses out many cooperation opportunities.

Another point: If we want to counter the assholes plan of monoplizing this worlds ressources in their few hands we urgently need to learn cooperation outside of state controles rule sets again… this sentiment is one of the core problems why the US is just taking Trumps shit and its population is far away from taking action: They’re devided and told to not trust anyone anymore. On this basis no revolution can be build.
