That part, I already understand.
But you needed to have some sort of excuse for such things back when smartphones were new.

I think the compartmentalisation concepts were there from the feature-phone era.

Don’t they also have some NFC payment stuff there too?
Though that’s probably connected to the debit/credit card and not really a separate interface.

If you have a smartphone, you get to use UPI (United Payments Interface).
If you don’t, you are basically limited to a certain amount of free withdrawal per month, which is set to prevent getting an outcry from BPL (below poverty line) people, which would otherwise be bad for elections.

I was considering pushing for open source UPI apps for Linux devices (and providing my services for development), to reduce India’s reliance on Google and Android but considering recent events, I believe that is not really going to align with the Government’s plans.

This doesn’t make sense to me.
Why do they even need it to be that way?

Compartmentalisations was one of the basic points in system design methodology that I thought (because I read it somewhere) smartphones would also be built upon. So why compromise the whole thing to a supply chain attack?

They seem to have plans for those types too.
Withdrawing cash is going to be taxed.

Nah, they’re mostly just going to endlessly harass you for it and wait for you to bribe them.
They will randomly send dacoits in uniform to beat you up and jail you and make it harder for you to earn a living until they get their birthright bribes.

I initially started de-upvoting just because it felt weird to have a blue marker on my own comment, which was supposed to be for other’s comments that I upvoted. It then evolved into having a “reason” behind it. But yeah, it just seems weird to upvote one’s own comment.

Well, first you need to define a “person”.
Then you need to define the starting point and what all environmental features you are considering as zero cost.

Otherwise, to calculate energy to kill a person, you need to start by creating the universe.

On the other hand, for a human person, you can either just get a really big syringe and siphon out blood from the heart, or pierce a thin little metal pipe with tactically placed holes, which will let gravity and internal blood pressure do the job. But these require access to a syringe/metal pipe making setup, which has its own energy costs.
