My experience was similar in a few ways to PinkSparkly and Marsha.
I was sufficiency scared in the first few weeks of the first lockdown that I was willingly compliant (although I never disinfected shopping or quarantined post).
We were given to believe - although the virus was it was mostly dangerous to elderly and vulnerable - that any one of us, including children - could die of it.
After a month or so, I no longer wanted to be compliant, but I was forced to be. Everything apart from "essential" shops and services were closed and we were led to believe that the police were patrolling every street corner and prosecuting anyone who strayed too far from home.
In order to meet up with people, you had to find others who were willing to break the law and expose your own willingness to people who might judge you negatively. No one I know admitted at the time that they would have or did break the law.
That is why I remained compliant pretty much to the end of restrictions. Not because I agreed with them, or that I was scared anymore, but because I feared the disapproval of others.
Fear of death and fear of the disapproval of others are powerful motivators and were used effective weapons against us during the lockdowns.
