if you leave it to industry to pick their own direction and comfort zone, it would be like how industry managed every other sector which does not have $ billings in our market, there is no incentive for them to think big, outside a few biggies like TATAs, reliance and ITC.
take basic sector like banking, internet banking and debit/credit cards for example, banking the unbanked used to be such a big topic of discussion a decade ago. gyanis used to give us lectures about third world economies being unbanked blah blah and banks (including SBI) used to say it's not profitable for them to open bank accounts for everybody . it's the gormint's nudge using JAM trinity that changed the whole game and turned it on it's head. now almost every family and everybody has a bank account, and we do 50% of world's online transactions because of fintech revolution that happened post UPI.
now all those gyanis have shut their mouths, haven't they?
if it was left to the industry, they would calculate as per their profitability and service only the regions which are profitable for them.
you seem to picking topics where gormint in involved, try picking a sector which has no $ billing (purely domestic market) where gormint is not fiscally involved and compare the time it takes to scale up for country our size.
