My dear, then there cant be any roads, rails, industries etc. where u need huge stretch of land and even if a single individual doesnt agree...the whole project will stop. Btw, Indian constitution allows govt. to acquire the land ofcourse supreme court ensures that they are properly renumerated and relocated.
And, you mentioned govt staying away from religion as secularism. Indian constitution declares indian secularism as non-religious and not irreligious. So, its basically allows religion based differentiation and not religion based discrimination
