This is an interesting take and good advice for those who probably do not need to ever worry about becoming destitute. I’m sorry but too many of your options including your own list of income require quite a bit of initial investment/capital and these suggestions are useless to those living paycheck to paycheck. I’d like to see the average low to middle income household purchase additional property for rental, invest in their portfolio (if they can even start one), or even afford to have a vehicle or room to rent. Far too first world of a solution for the general public.

Once I started blogging and connecting with other bloggers in the personal finance space, I saw how much potential was out there. And honestly, how much money some bloggers were making really shocked me. I distinctly remember one blogger telling me his website was making $30,000 per month….and this was 2009! To say this blew my mind is an understatement of epic proportions.
What I Do: I’ve set up multiple investment accounts outside my main operations bank that deals with working capital e.g checking, paying bills. By transferring my money to a couple brokerage accounts and two other banks as soon as it hits my main bank I no longer have temptation to spend on frivolous things. As a result, I can wake up 10 years later and reap the rewards of compounding. My 401(k) is the best example where constant contributions over 18 years has grown to over $500,000 without any savings pain given it just became a part of life. Real estate is also a fantastic asset class for the long term. It’s fantastic to enjoy your home, pay down your mortgage each month, and end up with a paid off asset that has likely appreciated during your time of ownership. 
India is a founding-member of General Agreement on Tariffs and Trade (GATT) and its successor, the WTO. While participating actively in its general council meetings, India has been crucial in voicing the concerns of the developing world. For instance, India has continued its opposition to the inclusion of labour, environmental issues and other non-tariff barriers to trade in WTO policies.[286]

Since the early 1960s, successive governments have implemented various schemes to alleviate poverty, under central planning, that have met with partial success.[342] In 2005, the government enacted the Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA), guaranteeing 100 days of minimum wage employment to every rural household in all the districts of India.[343] In 2011, it was widely criticised and beset with controversy for corrupt officials, deficit financing as the source of funds, poor quality of infrastructure built under the programme, and unintended destructive effects.[344][345][346] Other studies suggest that the programme has helped reduce rural poverty in some cases.[347][348] Yet other studies report that India's economic growth has been the driver of sustainable employment and poverty reduction, though a sizeable population remains in poverty.[349][350]
An obvious example is over exposure to bank stocks, which have been excellent investments for over a century.  Though a foundation of most portfolios, bank stocks do involve more risk at certain stages of the economic cycle than many realise.  Being less exposed to bank shares in the last few months could have preserved some capital.  So, a more diversified approach can help mitigate some of these risks.
