Just a bit off Local perspective. I am a pensionist in EU. Little cash. To walk the camino I need to cook,pretty much all the time. As a result I will be carrying a stove
As to,whether or not it will be allows on,the plane I know not. I own 4 MSR whisperlites, including the very,first model. I usually buy a new one for flying. This time I'm not bothered. Whether airport security will confiscate it ir not I do not know. I also have a gas pocket rocket.. Weighs nothing. However as far as security,goes I will post again here. I will if its all confiscated just get something usable in France.
People use money to avoid problems. I have to eat. With fire I cook. I am a pilgrim, not a,tourist. Ian,amongst other things high,altitude Himalayan guide. Now I am,a sannyas. An ascetic. So I survive on faith in humanity,water and a little food. All this light weight stuff seems to me to,miss the point. A stove, a little fuel, a little food and water. Salt and sugar. Very fundamental,and very very much allowing the freedom,to choose. Some rice and something to go with it. Half an onion, a quarter lemon. Some salt and chilli. Maybe something else. Ok.
All of you use western material philosophy yet in the old days one just walked. One became an ascetic. So gear ,rucksacks clothing etc are all illusions.
However fire is of fundamental relevance to us both now and for thousands of years gone by. To have fire gives a chance to survive, without bocadillos, menu del diaz, and so on. Simplicity focuses the mind. What is it I really need. Albergues are elitist and modern. Pilgrims did not go from albergue to albergue. The rich could afford things. Your local pilgrim could not.. So I would say a small stove, a pot, a little food and water carrying capacity are essential to any traveler. But then money will get you out of many physical hardships. Choose. Do I really want to be limited to getting to an albergue and only then eating what I can afford. If they gave a kitchen, and knackered from,walking. For a few grams the freedom exists. Use it. The camino is a pilgrimage in it's essence. Not really a tourist trip. But exercise the privilege of being a free human being. Make the choice yourself. A little stove and fuel is worth it. I've used mine in Singapore! ( where there is great food available ready made) and all over the world. A small weight sacrifice for what you get. Fire. A very fundamental, yet taken for granted part of the necessity of human life.
Et godt camino,til jer allesammen.
