Fossil field are expensive relative to most renewable sources as well as nuclear. This was before the recent price manipulation by oil companies, which have grown price disparity.
If said policy change is a radical departure from status quo that allowed humanity to flourish since the start of the Industrial Revolution, then quite accurate indeed. People can't just bandy about phrases like "abolish fossil fuels" without justifying it with strong evidence.
Most climate advocacy, I find, focuses too much on the doom and gloom of what will happen if we continue down our present path, and not enough on the number of lives that have been and will continue to be enriched by easily and cheaply accessible energy from fossil fuels. I am aware of the downsides and by no means think we should pollute for the sake of polluting, but I remain unconvinced by the current alternatives proposed by the overall climate movement.
