Thanks for your entire post, but for this in particular:
The thing I like with alcohol stoves is that you don't need to transport a white fuel or canister stove when travelling by air. If you don't carry a stove, you won't get hassled by the TSA or equivalent. Simply empty a couple cans of pop or beer, cut, fit, make jet holes and add alcohol to burn! And at the end of the trip, just recycle the stove.
These days, that's a really practical consideration.
Add to that the fact that alcohol can be pretty easily obtained even in towns without a "mountain shop" type store.
