To make things interesting, here's a steelman argument for statists in India to keep everything as is:
Scrapping a tax, subsidy or regulation on day 1 is a terrible idea for sectors of society that are are reliant on those things to exist.
When you scrap a subsidy, you can't do it without causing beneficiaries to lose money if their business model depends on said subsidy in order to be viable. If the production of an raw material or intermediate production good itself depends on that subsidy, this would cause even more disruption further down the production line.
Far more disruptive would be scrapping welfare subsidies as people's survival would depend on the benefits to keep flowing. Scrapping it would amount to throwing them out on the street almost.
Scrapping a tax would be more or less disruptive depending on the tax in question. Scrapping GST would cause disruptions by affecting consumption patterns. Scrapping tariffs would threaten unprofitable and inefficient businesses in India. Scrapping income taxes would cause disruptions to the income of chartered accountants.
When you deregulate, you disrupt enterprises that depend on such regulations to exist. Introduction of competition would mean existing companies potentially going belly up, their investors losing money and their employees losing their jobs.
You cannot privatise a PSU without causing similar problems that deregulation would cause. And if you privatise without deregulation, it amounts to enabling a private monopoly which would likely be as worse as a public monopoly.
Relaxing Gun laws without improving the justice system would amount to lawlessness.
Privatising temples would likely result in upper caste folks taking over temples and barring entry for lower caste folks.
Privatising healthcare and education on a fiat standard would make both unaffordable for the poor over time.
Gold standard while having centrally planned interest rates would cause business cycles that cause booms and busts.
Relaxing labour laws would disrupt wages, job security and cause riots and strike by unions that damage property.
Enabling private ownership in forests and resources would lead to extraction and destruction of them by private owners even if they are locals.
