The point of the parent system is to prevent knowledge from being lost to humanity. It encourages disclosure on how unique and novel things work in return for a limited monopoly. If inventions were not patented then we can lose the ability to make them, which isn’t as insane sounding as you might expect.

Preserving this knowledge for the future of humanity is critical.

If you ever do a patent survey, you'll quickly discover that patents aren't written to preserve knowledge or disclose inventions. They're written to disclose as little as possible (or disclose everything except the thing that matters) as fodder for a legal defense.

Science journals exist.

OTOH, I’ve never, not once, ever, heard of someone reading through the patent database to learn how to do a thing. I’m sure someone has done such a thing, but that’s not the norm. The patent database is where you record that you were the first to claim to have done a thing. It’s not where you meaningfully explain how.

That may have been the point hundreds of years ago. Today, it no longer serves that purpose, and is doing more harm than good.

This is absolutely not the point of the patent system, otherwise there would be no provision for a monopoly over the commercial manufacturing of the invention.

Don't be deluded, the patent system serves as a weapon for bigger companies to block competition. That is their only goal.

You should always be able to make your opponent's arguments at least as well as they do, as that is the first step to overcoming them.

The argument from patent proponents is that without the legal monopoly, they would rely on trade secret law instead, so they would do their best to ensure no one else understood what they do. They still do, within the confines of what disclosure is legally required to get a patent issued (I once had an engineer tell me that if he had not invented the thing being patented, he would have no idea what the patent application the lawyers wrote for it was describing), but at least there is a legal requirement.

Of course, there are important contexts where that argument is irrelevant, such as standards development. Trade secret law is no use there, because the value is in the network effects of the standard, not the invention. Yet we still have patent-riddled standards.
