How does an ordinary user affect the decisions? I simply don't get it. If you're someone who protects the network, you ought to vote for a change, you're the transactions' validator. An ordinary node that doesn't help the network doesn't have an opinion. I could create dozens of nodes from different parts of the world and maybe even dominate in the majority of the tor nodes. What am I doing after all?

Yes, I follow the consensus rules by myself, but the protection of the ecosystem isn't done by me. Why should I vote and how many votes for a change do I deserve?
