There are probably tones of ideas that would be viable businesses if executed. One problem though is between "scratching my own itch" and "payroll bigger than my old day job" is working "4-6 hours every night after work, entire weekends, holidays". And even that is no guarantee of getting to a big payroll (another thread is discussing persistence vs stubborn).

Not many people are even in a position to do this (family, health etc), or have the mental and physical energy to do this for years. This is one of the potential benefits of something like UBI. It allows people to pursue these ideas without having to work another 9-5.
