> as why getting carried away by the words fundamental right is something to be cautious about.
Because people sometimes tend to equate "fundamental" with "absolute", and assume that the right cannot be taken away from them under any circumstances. That is not correct.
> You didn't mention what type of restrictions can be put
What is a "reasonable restriction" has not been defined unequivocally - it is subject to interpretation of the courts.
Apart from declaration of emergency, which is an exception circumstance, when has the fundamental right been taken away? Why are you giving extreme examples to prove your point? The last time fundamental rights were taken away from Indian citizens was in 1975.
Fundamental rights are not absolute, in the sense that reasonable restrictions can be placed on them.
An example is Article 21 of the constitution:
No person shall be deprived of his life or personal liberty except according to procedure established by law
So a person's right to life or personal liberty can be restricted according to procedure established by law. That is why you find people in prison. Their fundamental right to liberty is restricted by a procedure established by law. Similarly, the fundamental right to privacy can be restricted by a procedure established by law.
Because people sometimes tend to equate "fundamental" with "absolute", and assume that the right cannot be taken away from them under any circumstances. That is not correct.
