I can only respond to the part of your question that is coherent to
me. The "how would that work?" part feels ill-formed and something
I've already answered.
But "Why would crime become constant?" is very interesting. For that
we turn to "criminology" [0,1]. Roughly, there are three "layers",
biological, psychological and sociological. All of these are either
fixed, or very slow and hard to change.
Indeed the biggest factors in "how much crime there is" are laws and
reporting, how visible the crime is. Obviously we could make crime
disappear overnight by declaring all behaviours legal. Really, the
justice system can only absorb and respond to what the underlying
social and economic conditions set.
Most crimes are resource motivated [2]. Violent crime makes headlines,
ruins lives, changes votes and is generally undesirable. "Soft" crimes
are less visible and have less impact, especially when they are
against actors that are so immensely wealthy they do not even care
(for example big-tech companies that see huge fines as simply the cost
of doing business as usual)
When we have a fixed pool of criminal potential (set by these
structural conditions), which would you choose as a new criminal
entering the "market"?
And not surprisingly, Pew Research polls showed "violent and property
crimes declined by 51% and 54%, respectively, between 1993 and 2018."
Therefore the hypothesis I was curious about was whether Removing the
opportunity for cyber crime (via better security) would have the
unintended side effect of shifting crime back into physical robbery
and theft with its attendant violence.
What do you think?
