Burning biomass instead of coal for the same reasons seems stupid to me. Like lets burn inefficient coal precursors instead of coal. Doesn't move the needle much in my opinion, with the argument being the trees grow back in 30 years.

Wood sequesters carbon once it is put into permanent geologic storage, otherwise it is just part of the normal carbon cycle in the biosphere. Any individual tree will temporarily take carbon out of the atmosphere, but could release it back to the atmosphere at any time if that tree is burned or becomes deadfall without being buried.
Trees die and rot if they aren't used for materials, or buried by sediment and locked away in a petrified form. And when they do rot, methane is the typical form of emission, so that's kind of worse from a climate forcing perspective.
Putting particulate matter (PM>2.5) in the air is bad, period.
