It’s always an option. It’s a similar but different comparison to those looking to move off gas. Many with gas have ducted systems to heat a whole home, and use gas for hot water and cooking. Most using wood likely only one area, some as a necessity, most not continuously or day long except on the coldest of days.

Heating using a wood fire is a continual chore. Well seasoned firewood provides around 20MJ/kg. How that equates to house hold heat output depends on how one burns it - open fireplace, wood heater, etc. The efficiency of an enclosed wood burning heater or stove can be as low as 50%, IE 2-3kWh of heat output for every kg of wood. Some boast 80% or higher. The older the appliance the less efficient and potentially dirtier the combustion.
