I am with you more than you know. I was in the anti-war protests before the Afghan invasion. The war had 80%+ support in America and only about 200 people showed up to protest. When I would say that this might take 20 years people would laugh and say "more like 6 months." That was 14 years ago and we are now further behind than ever.
However the real cost is yet to be counted. In the mid-east your friends and enemies are for life. Because most casualties of war are civilians we have made a lot of enemies. Even when the enemy is the one hurting people many will blame us because we came from halfway around the world to get into their business. We might think it's acceptable to kill a civilian to get to 10 bad dudes, but what if it was your brother? You might just decide that the Americans must pay and join the enemy. What have we gained then?
I would like to see us cut our military in half and start extricating ourselves from being the world police. We aren't any good at it anymore and it is harder than ever to find someone to even side with.
As for taxes... It has been calculated that if 5% of Americans choose to not file it would be impossible for the IRS to process them before the next tax season. What if as a protest we all file 1 month late? Our only real power anymore is that congress and the senate need our money to enrich themselves. It's the only pain they seem to respond to.
Great, I figured this might be the case but part of convincing 5 % of Americans is to not assist them in spreading the fear states love promoting. What you said was correct and we shouldn't play down the risks or threat of the state, but we should also raise our standards as well where we risk the potential of jailtime and/or fines in the service of limiting the amount of murder, torture, kidnapping, and oppression states are involved with.
I understand that fear is a greater motivator than altruisim, what bitcoin shifts is the incentive structure where you no longer have to be a millionaire to lower your tax exposure with loopholes, offshore accounts, trusts, ect and now everyone has the ability to lower their risks and have a fighting chance of not participating in these human atrocities.
The federal government had become a monster and people are genuinely afraid of it.
I am not telling people what to do or giving out legal advice and the risks are indeed there but often times exaggerated.
If you live in the US it is good advice to file your taxes correctly, but there is no legal requirement that forces you to claim every deduction either. If you have been a victim of a failed bitcoin exchange where your savings were lost or you made the mistake that many of us have made by forgetting to backup your wallet and your computer crashes than you are not required to claim these deductions and there are reasons why you may choose to avoid doing so as well. Keep your books clean and sanitized and detailed records and an audit can be scary but you will likely make it through as long as you are not lying or made any mistakes on your filings.
