First, the clearly redundant phrase is “applicable laws” - these apply to everything.
Second, some acts, particularly consumer protection or sale of goods acts imply provisions into a contract, create obligations that sit beside the contract or create equitable remedies. Many of these can be limited or excluded but this needs to be done explicitly.
Third, in legal writing, clarity is preferred to brevity - nice if you can get both but if not, be clear rather than brief.
Fourth, the contract is not the document. The document is a record of the “meeting of the minds” that formed the contract. In the event of a dispute, it may be useful to know that particular laws were specifically considered by the parties.
Fifth, in legal writing, just as all writing, some people are better than others.
