You can't fix a broken system by using the means/tools that same system supplies you to do the job. It's a rigged game.
We are in the VERY early days of blockchain and decentralization. There will come a time when people are going to have to make a decision to either support the old dying system or a "new model" that gives them more choice and more freedom.
I don't believe it's entirely rigged. I do think we can elect politicians which are favorable to our interests. I promote using all the available legal and ethical means to get things done.
