I have issue with much of what you've said:
"...in supporting the erosion of privacy..."
I wasn't tarring everyone with this brush. I don't support the erosion of privacy, so it would be hypocritical of me to tar anyone with this brush, let alone everyone. Much of my family for instance believes in the "I've got nothing to hide, so I have nothing to fear" argument, but my perspective is "neither did the Jews before Hitler".
> Some people, rightly, hold themselves and others to higher standards.
You cannot control the actions of everyone else, only yourself. Others will do what inspires them. What inspires them may or may not align with what inspires you. When it doesn't, expecting them to abide by the rules you hold dear is only setting yourself up for disappointment.
> People even abide by the rules
Yes, when it serves their purpose. When it doesn't, they either break the rules publicly, demonstrate to get the rules changed or break them privately to avoid judgment or being ostracized by partners, family, their community and hope like hell they don't get caught.
Lines are drawn regarding all kinds of things. Let's take just for the argument's sake, speeding, or smoking marijuana, never downloading music or movies illegally - things that we can all agree, there are rules about, rules that (currently) define these activities as prohibited in many jurisdictions. Even though there are rules, and many people may argue they're dumb rules about benign activities, there are still rules. Many break the rules publicly, voicing their defiance; many others break them privately and hope they don't get caught. I'd say given your stance you never break any rules - even rules you consider dumb or counter to your own set of beliefs or don't align with your interests; you always abide by the rules and you always fall in line with the wishes of your neighbour. Of course you don't, nobody does. It's human nature to question the rules and to find loopholes, and to bend them and/or break them when they don't align with our interests. These rules, which are defined for the good of the masses, to maintain the status quo. But what happens when what's good for the masses doesn't align with what's good for you? Do you put everyone else first or do you put yourself first? You put yourself first, you hope like hell you don't get caught or called out; or you hope if you do get caught you get away with a slap on the wrist or that a reasonably competent lawyer could fight your case in court and help you avoid the charges.
For me to believe that you strictly abide by all the rules, without questioning human nature, and without understanding your set of circumstances, would be incredibly naive. There are many reasons people break the law, it's not always cut and dry nor black and white. Most of the time it's incredibly grey - to the point that billions of dollars every year are spent on lawyers to argue to put people in jail or keep people out of jail based on legal technicalities, loop holes and precedence set by previous circumstances; because nothing is black and white. If it were then anyone could go to court and defend themselves and no more lawyers would be required.
Some of those revered as the greatest people on earth shunned the rules to invoke great change. Some canonized as saints after the fact, but in their time considered rebels, misfits and, in some cases, criminals: Rosa Parks, Bob Dylan, Mahatma Ghandi, Einstein, Martin Luther King Jr., John Lennon, the lone protester at Tiananmen Square, Nelson Mandela, heck, even Jesus Christ - the son of man, shunned the rules and defied the status quo because of their beliefs - and many believe their rule breaking changed the world for the better.
