[Star Wars] On Tatooine, why don’t settlements like Mos Eisley have walls to protect themselves from Tusken Raiders?

1. Big settlements like Mos Eisley are not in danger of raids, any raid big enough to pose a threat would be seen approaching from a large distance.

2. Walls aren't that useful in the desert. There is no real way to set a strong foundation that cant be dug under, and the constant windblown sand buildup would require you to go shovel clear the windward side of the walls regularly in order to prevent natural ramps building up.

3. Tusken Raiders prefer small hit and run attacks on travelers and households that are encroaching on their ancestral lands, they are not mindless roaming monsters looking to kill and loot whatever they can.
