Brokers License in California?

Is it necessary to have a real estate brokers license in California in order to flip properties?

I have been assuming there was no license necessary. However, California Code 10131.1 indicates that an individual who buys or sells more than 7 real estate contracts per year is required to have a brokers license.
This means that both a wholesaler and a retailer need a license if they buy or sell more than 7 contracts per year.

Please clear this up for me.
