Asking the gov to proactively shrink or limit animal products is a non-starter because there are just too many (voting) consumers who would be outraged. It would be political suicide. Same for cars. Forcing car owners out of cars would be political suicide as well.
But what I find baffling is there seems to be no chatter about the fact that the US gov gives (millions?) in subsidies to livestock farmers. And Europe gives tax breaks for “commercial” cars (mischaracterized personal cars). If the gov were to end the subsidies, there could be no reasonable complaint that the gov is interfering. Because in fact the gov would be ending their intervention.
Since you said “car centric transport infrastructure”, and zoning, that really sounded like the US. The US has some really fucked up zoning that forces commercial buildings to be separated from residential zones, which forced the norm of driving cars to work. Europe allows homes and businesses to intermingle. In fact, it’s common for a ground floor shop to have residential dwellings on the floors above it.
