Obviously it’s not 100% meaningless, but the kind of people losing their licenses here correlate with the kinds of people who will take these risks.
Thus for many it’s a symbolic gesture until the next time something happens which is little different than simply doing nothing until the next incident like say 3 strike laws.
I think that is probably true now (in the US), but the hypothetical is that it is made easier to lose your license.
DC recently banned "right on red" but it is routinely ignored and the penalty is apparently a $100 fine. If the penalty was loss of license (maybe not on first offense) I think there's a lot of people ignoring the current rule that would not be willing to ignore the possibility of losing their license.
