Rationing Our Way Out of the Climate Crisis?

Actor Joanna Lumley is probably right when she says that 'wartime style rationing could help solve the climate crisis' (https://www.theguardian.com/environment/2021/oct/26/joanna-lumley-wartime-rationing-solve-climate-crisis). Why should a relatively small proportion of the UK population, utilise most of the country's air flights? Why should some people restrict their meat consumption, whilst others wolf down animal protein every night? Why should some people replace their emissions-heavy domestic gas boilers, whilst other use patio heaters in their gardens? It all sounds very straight foreward. Rationing was, however, easier to set up on an island like the UK in the Second World War. Everyone carried identification. All were citizens or people whose presence in the country was known and approved. In spite of a general acceptance of rationing into the 1950's in the UK, there was trading of allowances, a thriving black market and even counterfeiting of coupons. Money could, even then, get around any restrictions. Rations also resulted in some people, because of their position, receiving more than others. This caused resentments. There would certainly be powerful arguments for entertainers, politicians and captains of industry etc to get bigger allowances for travel. One might also predict that getting a country to ration, could be difficult if conspicuous consumption is seen in other nations (it will be). It is hard to see rationing working unless it is adopted on a global basis e.g. for air flights. There is no sign of general support for such moves.
