There's an inherent problem with an increase in people who don't have clear geographic roots.
Game theory shows that when people expect single-iteration transactions, they tend to defect on others; and when they expect multiple-iteration tranactions, they tend to cooperate with others.
"Single-iteration" means "I'm not going to see that guy again," and "defect" means "so I may as well screw him over."
"Multiple-iteration" means "I'm going to have to deal with that guy again and again," and "cooperate" means "so I ought to play fair" (either on the basis of principle, or for avoiding a penalty).
If you have the ability to keep traveling, you can create a scenario for yourself where you can minimize the probability of interacting with the same people more than once. In this scenario, you can screw others and keep moving, and chances are they won't catch up to you.
If you're geographically rooted in a stable community, you interact with the same people again and again. In this scenario, you have to play fair or people will stop doing business with you. This scenario doesn't eliminate competition per se, it just creates ethical boundaries.
This (single-iteration / defect) is the basis for the stereotype about gypsies being con-artists and thieves: enough of them were, that the rest got tagged with the label whether they deserved it or not.
Traditional nomadic cultures have ethical rules governing their conduct with members of their own culture and with other cultures. These rules evolve over generations and select for behaviors that enable the nomads to continue to exist among geographically-rooted cultures.
In a situation where nomadicism is sudden and involuntary, without a history of nomadic ethical rules, there is a greater likelihood of various forms of criminality breaking out and becoming commonplace. This in turn will lead to hostility toward nomads in general. The situation could be ameliorated by systems that enable nomads to provide immediate and verifyable reputation data to others, and thereby establish trust and acceptance in business dealings and social interactions.
