Flagging tape is a pretty temporary solution. It might last a season but degrades quickly in sunlight. Painted blazes will usually last for several years and is why its used extensively in the Maine woods and other places. Property owners don't want to be doing it time and again so they use what has proven itself for generations.
Lots of hunters flag their paths to a hunting spot in summer only to return a few months later, usually in the dark to find many of their tapes missing from blowing winds and sunlight degraded plastic.
