Is starting a business just opening a shop to do business?

Entrepreneurship must be doing business. But opening a shop is not necessary.

In the Internet age, you can sell your products or services in any form.

E-commerce micro-businesses are doing business. Their most fundamental thing is to do business, but they don't need any physical stores at all, so they do better than those with shops. There are also stalls, entrepreneurs and businessmen, and there are no shops.

In short, starting a business is doing business, or more bluntly, selling things, which can be real goods or invisible virtual services.
