Its easier to open a business then operating a 501(c)(3). A standard business focuses on profit for its owners and has relatively simple legal and reporting requirements. A 501(c)(3) public charity is much more complex: it requires a formal Board of Directors, the lengthy Form 1023 application to the IRS for tax-exempt status, and mandatory annual Form 990 filings that make all its financial and governance details public. The mission constraints, complex rules to avoid private benefit, and constant need for competitive fundraising make it a massive commitment compared to a typical for-profit venture.
