No, we don't need to change that. You're on a tourist visa. You arrive on day X and you leave on day Y. If circumstances change due to events out of your control, then there are solutions for that.
You want better terms, improve the situation in India. Favorable terms are given to citizens of countries where they're unlikely to violate the terms of their visa, like overstaying the validity of their visa.

There literally are no good solutions to that. I went through the whole rigmarole of getting a schengen visa for a specific week and then had to postpone my trip by a week due to change in business plans. The 'solution' was to get a second schengen visa for that second week, by submitting the same documents again and paying the same fee again. Which involves showing up at a consulate in-person. Which are not in every city. (source: https://manila.diplo.de/ph-en/service/visa/faq-gq-change-vis...)
Literally nothing would be different if they decided to grant you the visa for the duration you asked for but allowed you the flexibility to make that trip within a time window. You would still ensure I'm in EU for a limited time, but allowed some flexibility.
Secondly, none of the measures like asking me to show booked hotels or booked flights actually ensures I wont be overstaying. I could very well show you all of those and overstay if i wanted to do so illegally. All it does is forces people to shell out of a bunch of money even before they can be sure I'll be granted the visa.
you seem to have strong sense of ownership on your land, maybe your ancestors owned that land for very long time, but keep in mind that your ancestors came from somewhere and nobody denied them the right to stay and live
Around the 13000 years. The previous significant inhabitants left or were wiped out due to the ice age. The idea of a country was established in 800AD.
The concept of visas may not have existed at that point in time, but you were at the mercy of those in power. If they didn't like you, they'd banish you from their lands or worse.
The modern rules are entirely based on statistics. How many overstay their visa. How many get denied a visa. Are compromised passports swiftly dealt with. India doesn't live up to the rules for easy visas.
You go sit in the airport after your passport has been exit stamped. No, you can't stay in the country after the expiration of your visa, unless you have a very good reason to do so.
