Weed is a category B drug in the UK: https://en.wikipedia.org/wiki/Cannabis_in_the_United_Kingdom
This means "with penalties for unlicenced dealing, unlicenced production and unlicenced trafficking of up to 14 years in prison, an unlimited fine, or both. The maximum penalty for possession of cannabis is five years in prison and an unlimited fine."
The police absolutely try to enforce this: "In the survey-year ending March 2014, possession of cannabis offences accounted for 67% of all police recorded drug offences in the UK."
Despite this, "In 2017, 7.2% of 16 to 59-year-olds reported using cannabis in the last year, making it the most commonly used illegal drug in the United Kingdom."
If this law, all by itself, was perfectly enforced, the UK would bankrupt itself just on the extra spending in the prison system.
That conclusion ignores the interdependence of those effects. If people knew that it's going to be perfectly enforced, then almost nobody would do it anymore.
(Not that I'm a proponent of this particular law; just pointing out a flaw in your argument. Somebody wrong on the internet -- gotta reply!)
Speeding laws are good when the stop that guy from endangering my kids. Or when they generate revenue from tourists.
Those same laws are awful when they inconvenience me.
Regarding those first 25 years or so: Jefferson's attempt to ban slavery in 1784 failed by 1 vote. Then there was the Whiskey Rebellion in 1791 and then the Alien and Sedition Acts of 1798. So, nothing's perfect I guess...
Red light cameras should effectively catch 95%+ of people who blow through them. Speeding cameras (that are actually on, looking at you NYC) that are super visible are a known deterrent to speeding in Europe. Even parking - in some modern garages they have sensors to tell you when spots are full/empty. Why can't they use similar tech for parking tickets, street cleaning, etc?
I feel like I wouldn't be upset about rule enforcement if I knew everyone was more or less following them. What makes me ignore rules is when I see people taking advantage of them over and over without repercussions. Then, introducing human elements where the cop gets to decide who to ticket adds a bunch of bias that we haven't been able to correct. It's one of the countless examples of humans over-complicating things to the point of dysfunction.
But what's common is that infractions are so widespread that there's a massive backlash and the programs get cancelled. There was an automatic speed trap on the interstate just south of Pittsburgh a few months ago, set up along side some temporary construction with reduced speed limits. A few weeks later there was a headline that it had generated so many tens of thousands of tickets that they were considering it an error and throwing out the tickets.
On this basis, the only people who would be allowed to drive a month after perfect enforcement starts, would be people who don't drive (plus the Queen because monarchy).
(Outside the hypothetical, the imperfection of the UK's speed cameras is such that the only ticket I've received was for an event that happened six months after I sold the car).
IMO the points system is as much about punishing people who depend on driving a lot as much as it is about punishing unsafe drivers.

Yep, this is absolutely what happens. Very hard to get people to self-sacrifice and cooperate if there isn't enough momentum.
One of my favorite things to do on 55mph PA highways near Philly is to go the speed limit. All other drivers on that road are going 75-85mph. They treat you like a terrible person for going the speed limit. But eventually one person slows down behind you, then another, and after about 45 minutes, there's a line of cars going the speed limit, while people zooming by wonder if they should slow down.
Drive the same speed as the other traffic or take the bus. It's safer for everyone that way.
But, my comment wasn't meant to imply traffic is the only place this happens, it was just an easy example. We see the same with (building) code enforcement at all levels from HOA to city/town/county. We see excess policing/enforcement (to the point of infringing on individual rights) in certain neighborhoods and with certain ethnic groups (stop and frisk in NYC, for example).
It's the same reason we veered away from using the metric system at the gas pump: changing things went along with outright gouging. Too many venal actors in the American system.
