With all due respect, I disagree. I've travelled my whole life with either a backpack, or a bloody great tote bag. Suddenly, 7 pairs of socks and 3 tshirts isn't enough for a big holiday, and rummaging through crumpled clothes seems a pain in the arse, rather than just something you do when travelling.
Hence the need for a suitcase, and the sign that maturity approaches.
