It is suggested that since distribution transformer links the primary and utilisation voltage, secondary
system is not essential. Is it a feasible proposition ?

No it is not. Transmission voltages are very high to reduce i²R losses transmitting 1000's of MW of power. Distribution systems can be lower voltages with cheaper distribution because they deliver less power. Transformers are required to efficiently convert to lower, cheaper to manage voltages. XFMR's are not cheap so it would be great if there was a way to eliminate them or reduce the number needed economically.

Sounds like a really bad proposition. Using 230kV as a local distribution voltage would make for very bulky transmission system (large insulators and physical standoff) and very expensive transformers. Much better to have the local distribution in the 5kV to 15kV range. Very smart people came up with our present system over 100 years ago for a reason.
I'm sure Wikipedia has an excellent article on power transmission.

How are you defining 'secondary system'?
