Gile manifesto what are the downsides

The Agile manifesto is based on 4 core principles which predicate priority of a number of elements OVER others i.e.

Individuals and interactions OVER processes and tools
…HOWEVER shouldnt we have mandatory processes and tools?

Working software OVER comprehensive documentation
…but aint this applicable only as long as that software is comprehensively documented?

Customer collaboration over contract negotiation
… However aint this in the boundaries of strict contracts, and subject to rigorous change control?

Responding to change OVER following a plan
… HOWEVER, aint this subject to a detailed plan being in place to respond to the change, and as long as this plan is followed precisely?

Discuss the above articulate/justify arguments and opinions.
