Why do think that entrepreneurship now depends completely on digital marketing?

Because there are a huge number of Internet users who spend a lot of time on their laptops and phones

I won't say that entrepreneurship depends completely on digital marketing as that would be a false statement, we could say that digital marketing is growing rapidly in this digital age but traditional marketing is still very strong but it is not for everyone, digitial marketing has opened doors for new entreprenuers to promote their products and/or services at cost effective solutions. However, the perception that digital marketing is cheaper for everything is again wrong, I have worked with budgets of USD 12000 per month with online Ads and I know people in the industry who have spent much more than that. Traditional marketing is still very much alive and kicking and it will remain so, however, digital marketing is and will grow rapidly in the coming years.

First of all, digital marketing is infinitely more affordable than traditional offline marketing methods. An email or social media campaign, for example, can transmit a marketing message to consumers for the merest fraction of the cost of a TV ad or print campaign, and potentially reach a wider audience
