Let the vehicles run, let the businesses run....
Let us develope some mechanism of protest where everybody can participate. It will be more effective than the street protest alone. There will be no curfew and people will move in again. Not every soul in this country can muster enough courage to be out in the streets.
If you let the common nepali work and at the same time protest, more people will come. Something like wearing a black band and carrying on with the work for few days will be more effective. If it does not work, you always have the streets.
