My friend, the only thing that's going to diminish is public services that actually help people. The police state is the primary state organ dedicated to protecting people with political power from the hoi polloi, it's the one thing that's never going to go away.
If the past few thousand years of history is any indication, these people will wring every last cent out of you to pay a professional warrior class that will protect them from you.
I sold my car and have been at peace ever since. No more tickets. Believe it or not, but even when I lived in the distant suburbs, it was generally feasible to bike to the office, particularly if one lives very near to work. Now I live in more crowded suburbs where I can rely on Uber/Lyft or public transportation. If I had to purchase a means to transportation, it's most likely to be an ebike, potentially even a three-wheeled one. The main time when they aren't good enough is in deep winter when the temperature is about 10F or less. Always wear a helmet and highly reflective clothing when on these things, and mind the speed.
In your answer, please stick to to concrete harms to actual people (living now or in the future) excluding any harm that is a harm only to an abstraction like Democracy or Freedom.
Solving crime is hard work, and dealing with criminals is dangerous work[1], and why would you work hard or risk your life[1] when you can do neither (and can instead brutalize or harass law-abiding people who won't fight back)?
In Seattle[2], emergency police response times are, on average, 70 minutes. Non-emergency response times are 3 hours.
(Meanwhile, the city's third-highest-earning cop was cited for falling asleep in their patrol car in a bus lane, while clocking in overtime. She should be breaking rocks with her teeth in state prison for overtime fraud, not given a badge and a gun... But the whole department is rotten to the core.)

[1] Of course, America's cultural obsession with guns and violence means that cops often assume that anyone they are dealing with is actively planning to murder them... And are quick to pre-emptively use (in)appropriate levels of force.
[2] Which is not overrun by 'Rampant Crime' despite what professional liars on television zooming in on a single burning trash can might say.
Yep. There. FTFY. And you're welcome.
