And how do you deal with households where the members have different work places? People change their jobs a lot these days, so does that mean they have to relocate with every new job? And wouldn't that be the end of settled and stable communities? I find that all a bit slippery to deal with.
Those very long commutes didn't come about by chance. To a large extent they have become commonplace because of the cheap current cost of energy to society (both manufacturing and private individuals buying fuel for their cars). In part the energy is cheap because we are using fossil fuels which are a finite resource at an excessive rate, and partly because the true costs of using energy and resources to create and incentivise such behaviours as very long commutes are 'externalised'.
Externalised because the full impacts of cheap energy etc. are not covered by the price we have been and are paying. Those impacts are both current and existing - e.g. a negative and vicious cycle of more roads which allow even longer commutes, pollution etc. - and future - i.e. harmful climate change. The latter is the same as a government borrowing excessively to pay for election bribes like large tax cuts or similar: the cost of the borrowing is passed onto future generations who will have to pay more tax to cover the interest on the higher resulting National Debt. Ironically that sort of fiscal irresponsibility is usually something firmly resisted by right wing politicians and commentators, but they are often the group that is most resistant to policies which will reduce the future impact of climate change (which possibly explains why so many of them refuse to believe in man made climate change, despite the overwhelming scientific consensus).
We either start making some very sharp course corrections, e.g. by significantly reducing the externalisation of those costs to discourage such behaviours, or we carry on as we are and say that things are just they way they are and that we cannot magic them away. The problem with the latter approach is that the costs we are continuing to build up for the future will have to be paid eventually, and the more and longer we put it off, the worse it will be be when the final demand arrives.
