Put another way, you aren't scouting ahead if no one is following you. You're homesteading. Which is a fine thing to do, but it won't get any significant bridges built. You, alone, won't be able to span the Mississippi with resources you find on your homestead.
I think we have entered a post trust era.
All that said, democracy is a team sport, so zero trust seems to be the population level consensus. So it's what should happen. Maybe it ends well? More likely it ends poorly. But either way, others will be able to learn from it and other human societies will benefit from the knowledge.
