Let shops open during Easter!

Easter time is supposed to be about peace and celebration, but it isn't for shopkeepers, who, once again, have to close down on "Good" Friday because of silly a primeval law the government enacted fourteen years ago. Easter is a religious holiday, and not everyone is Christian. So why don't we give our shopkeepers their well-deserved freedom to open on "public" holidays? Why should they be denied their right to offer people goods and services on any day of the year?
