Even ignoring that, dry wood is only around 50% carbon. I guess the soil mass is significantly more than that of the atmosphere, but I'd still want to fairly carefully verify we wouldn't be totally screwing something else up by also sequestering the other half of wood. Of course, we'd also have to decide where to place the new wooden mountain range.
I suspect some math is in order. A big truck can move a lot of carbon and I suspect there is some range within transport makes sense.
edit - To clarify if a big diesel truck puts X CO2 into the air to move Y tons of CO2 some distance then clearly if X is greater than Y it just doesn't make sense. But, if X is 10% of Y for 200 miles then moving biomass 200 miles might make sense.
Also the transport can be shrunk if the transport is electric. A diesel truck might dump less CO2 into the air than even a coal plant is dumping a ton of CO2 it might be dumping less (or more) per watt which might
Growing and sequestering enough biomass to slow down climate change means effectively running the fossil fuel industry at the same scale but in reverse. In that spirit, I'll point out that most efficient way of moving carbon-bearing solids per ton-mile is the bulk carrier ships we use for shipping coal.
