That's a touch harsh of an interpretation, most of us don't carry stoves if we can avoid the extra weight.
The Code actually says
"Lighting fires
Wherever possible, use a stove rather than light an open fire. If you do wish to light an open fire, keep it small, under control and supervised fires that get out of control can cause major damage, for which you might be liable. Never light an open fire during prolonged dry periods or in areas such as forests, woods, farmland, or on peaty ground or near to buildings or in cultural heritage sites where damage can be easily caused. Heed all advice at times of high risk. Remove all traces of an open fire before you leave."

Open glades, pathways, verges, stoney ground......Scotland is a big place and it's usually wet... the intent is care, responsible use, not don't ever light a fire.
