Question

Why is it NOT recommended that consumers acquire debts?

Answer 1

The more consumers have debts, means the more they have to pay back for what they borrowed (with or without interest).
It's not recommended because if they keep owing businesses or banks money, the banks won't have enough money to lend to other people who need it, and if that cycle continues, banks can go out of business.
Likewise for businesses who sell on credit. If people keep borrowing or buying on credit, having to pay back at some point, and they don't, businesses can't pay off necessary costs to keep their businesses going.
Also, the consumer itself may incur a bad reputation if it keeps borrowing and not paying debts, and may be kicked out of the bank or stopped from shopping from the people.
Also, it's not recommended even if you borrow at a small rate and pay back.. because at some point, inflation may rise, and the consumer would have to pay back a high sum than necessary. Also, in future, the money the person borrowed to spend, or the debt it incurred, was almost payable at the time of spending, but the person thought of just paying back later when they have the time to get cash... when they may not have the cash at the time recommended

and several more!
