You forgot to mention that harsh government policies can make a small business go under. A typical example which I remember clearly is Gokada. Gokada is a tech startup based in Lagos, Nigeria. The startup launched as a ride hailing company in 2017. And in 2020 the Government of Lagos State in Nigeria stopped the Gokada from working citing insecurity. A claim which made no sense. Even though, the company has now diversified into Logistics and Food Delivery, their ride hailing plan was the best because the company came with a very good initiative, where you can track their bikes to know where they are and where they are going. They are well registered. You can even track the bike from your phone, but the government cancelled it without a good explanation.
