I'll grant you that at least in Minnesota there are forms on the state website and available at self-help centers to assist parties in obtaining a divorce without a lawyer. That does not mean that failing to at least consult an attorney is a good idea. Every day judges review divorce decrees parties have agreed to without a lawyer. If approved, many of these are "an accident waiting to happen". By that I mean when the first dispute arises over an important issue like child support, spousal maintenance, or parenting time, it will be very unclear (and the parties will disagree on) "what was intended." As an example, if the decree is unclear as to under what conditions spousal maintenance terminates or may be reviewed, it is just possible that it will continue or terminate under conditions at least one of the parties did not expect or anticipate.
Provisions about property division must be particularly clear because generally such provisions cannot be modified by the court. So if the agreement says "We will sell the house and divide the proceeds," what does that mean? Who chooses the realtor? Who pays the mortgage, taxes and insurance pending closing? Who pays for what repairs and maintenance? What if a short sale is necessary? etc. etc. etc.
Sure, there are dozens of videos on YouTube about how to replace a toilet, replace a radiator on your car, or install an aboveground swimming pool. That does not mean that it's easy or that going alone will produce the optimum result.
