Wondering if there's any reason to not hold a bike in a bike stand by a carbon seatpost
Not any worse than clamping it in your frame .AllUpHill

I do it all the time with my alien post. If your frame's binder bolt doesn't crush it, your work stand's clamp doesn't stand a chance.
If you have ANY concerns...Atombomber

put a wrap of tape around the carbon post directly above the seat tube clamp, and replace it with a cheap alu post of the same diameter when working on the bike. I just got a Tacx Cycle Motion Stand which clamps the front or rear drop outs, depending on which end of the bike work is being done on.
Naah. No worries.Gregory Taylor

I put a clean rag in the jaws of the workstand clamp (I have a Park "Consumer" Stand -- Excellent bit of kit) and have at it. The rag keeps the jaws from scratching the gelcoat. You are not going to crush the post in the jaws of a doesn't generate that much clamping pressure.
no problem if precautions are used like the others saidTig

I've seen one guy who crushed his carbon seatpost in his home stand's jaws from over tightening.

I'd also advise to be careful when torking on a bottom bracket (installation or removal can generate some serious torque) when a fragile tube or post is clamped. An seat tube expander plug can help a little, but a second set of hands to steady the bike frame is best.
