Yes, that's because people have been spoiled by free and convenient parking for decades, so people are used to it. Not only that, but policies make driving artificially cheap and reduce the funding given to alternative transportation. Your experience is not unique to many urban neighborhoods because people are largely car dependent. But you still seem to not realize that building parking is solving the wrong problem - it's akin to giving addicts more drugs, rather than trying to remove the addiction. Having to park a few blocks away is a minor inconvenience; rampant automobile dependence, climate change, the hazards imposed by the automobile (the leading cause of death in the United States), and job sprawl, which separates people from job opportunities, are all a national crisis.

We have seen the opposite dreams become reality in less than 50 years. Prior to the mid-19th century, most people did not drive and most people lived in walkable places. Rampant automobile dependence was the result of several circumstances, notably heavy government funding of automobile infrastructure and policies that favor automobile-oriented development. We're starting to see these reverse, and the turnaround could happen just as quickly as suburbanization did. Many urban areas throughout the country have gone from places where you don't want to live or walk to places you could live your whole life.

I never said that moving to a suburban area will fix the problem for residents of your current neighborhood. I said that it will fix the problem of you expecting convenient parking near your home. I have seen your exact situation happen in other neighborhoods and other cities and trust me, I too get frustrated when I can't find a place to park. But I understand that that frustration is a good thing - if it was easy to park, my neighborhood would be less walkable, less sustainable, less vibrant. There would simply be less people walking around and more people driving. Many studies have shown this.
