No one is actively taking your gasoline driven car away. If you really need it, keep it. But for the largest part of the population, it might make sense to drive an electric car most of the year, and only for the few long trips into sparsely populated regions, they can rent a gasoline powered one.
Your argument is akin to arguing that cars are not usable for anybody, because there are some people living on small islands who need a boat to get somewhere else, or because once in a while, you need to go by airplane, because it would take too long to drive from New York City to Seattle. Yes, there are special cases, when a car is not a good solution. For those cases, we have other solutions. But that doesn't mean that we have to abandon cars. People living on small islands will not be frequent car customers. So what?
The same can be said for electric cars. Yes, there are special cases where they aren't a good solution. But for most people in most cases, they are. And for special needs, there are special transportation means you can use -- be it a gasoline powered car, a train, an airplane, a boat or a bicycle. It doesn't mean that you have to own all of them.
The Dutch Railways are now completely wind powered as of Jan 1 2017. Apparently they don't need baseload power plants.
So all warnings about the future and code reuse and upscaling are nice and dandy, but actually, I just ignore them.
So medium is now a small?
No, they've regressed to the mean.
You are messing two things up: deciding against air travel for a specific trip, and abolishing air travel altogether.You are trying to make the one be the same than the other. Many issues with air travel can be solved by simply having less air travel.
Coal is quite expensive and inflexible. It takes literally decades to open a coal mine, extract the coal and close it up again. And it is only feasible if there is either someone constantly requesting the coal, or if you have large storage capacities for unused coal, or if some governmental body pays subsidies for the time you can't sell the coal, and thus have to stop mining.
There is a whole bunch of offerings, which can be put together to achieve the A->B transfer, and you not using air travel is even a solution for some of the air travel issues of others. They get shorter waiting queues and more available seats for instance, if you are not there on the same flight.
And also for coal, someone has to pay for the land and subsidy. Coal doesn't fall from the sky (other than sunlight, which literally does so), it has to be mined, and beside the coal mines you need tracks or roads to transport the coal to the plants. So Coal is also a big consumer of land, especially if the coal is mined by surface mining, which is by far the cheapest option.
