Well, so are our immigration laws, which aren't being enforced. Marijuana is still (erroneously) illegal, yet Attorney General Eric Holder is choosing not to pursue legal action against banks who take deposits from admitted marijuana businesspeople.
The last time I checked, it was illegal for you or I to sell firearms to known criminals, and we'd be charged as an accomplice to murder if those guns were used to kill people. But the government doesn't even bat an eyelash at the botched Fast and Furious operation which ended up doing just that.
On a larger scale, it is illegal for me to forcibly take your money from you, yet the IRS has been directly (and illegally) taxing us into oblivion since 1913. I would be charged with violating your God-given and Constitutionally recognized right to privacy if I were collecting all of your phone calls, social media posts, and emails, but the NSA does these things to us all. I would be charged with false imprisonment and violating your Sixth Amendment rights if I were to lock you in a room indefinitely without giving you a jury trial, but the government claims this very "right" of indefinite detention. What's more, the government is now claiming and has executed the "right" to assassinate any person (even American citizens), anywhere in the world, for the crime of being "suspected of terrorism." This alone should send chills down every Freedom-loving person's spine: Either we all have the right to a trial by jury, or none of us do. Furthermore, It is illegal for me to poison you, yet the federal government protects biotech giants like Monsanto who are doing just that. You would be charged with counterfeiting if you printed your own money, but the Federal Reserve (private) bank has been granted this authority.
As a side note, and on the largest scale: If it is wrong for me to do "it," it is wrong for me to ask an agent of the state to do "it" for me. This is true whether it be forced taxation (aka: theft/slavery) or holding you at gunpoint to stop you from an activity that harms no one outside yourself (such as using cannabis or growing a garden in your front yard).
Bigger picture aside, the current administration's arbitrary and unilateral decision to selectively enforce laws has set the stage for lawlessness. And make no mistake: It may not be necessary to have a government to steal our money and start wars on our behalf, but it is important to live by rules that prohibit people from harming one another.
