Your argument is based on the false assumption that cooperation automatically implies collectivism. Collectivism requires the individual to submit to the group, whereas voluntary cooperation is based on individual benefit. Consensus is not a sign of collectivism, but rather a pragmatic agreement that everyone enters into out of self-interest.
Roads, houses, and computers are not the result of collectivist structures, but rather the product of individual innovation, free markets, and incentives. Progress arises from competition and personal motivation, not from collective identification. People work together because it benefits them, not because they see themselves as part of a larger collective.
The statement “Both the Bitcoin community and governments have the same goal” is collectivist because it suggests that both groups act as homogeneous units with a common, overarching goal.
