a monopoly patent was literally a government invention. an actual monopoly does require the government. what you are talking about is called a "natural monopoly" in the literature. that would be a situation where there's only one seller for something like say water in a desert town. in that case you can have price gouging and such.
now, the important bit is the LEGAL ability to prevent competition. if there is a natural monopoly on water, and the seller decided to start charging obscene amounts for water, those extreme profits would normally induce other sellers to enter the market. except when they are legally prohibited, we can expect that a natural monopoly will not last if what we call "monopoly rents" are extracted.
so you see, a true monopoly requires legal force, eg the state.
but almost no two libertarians will agree about those things. if you think there is only one "blessed" or accepted viewpoint on those topics, you've been duped.
for example on the rights of kids. there will be somebody who will argue they fully own themselves and parents are never allowed to hit children or otherwise harm them. then there will be some idiot who argues that because babies are helpless and the parents made it, that the parents "own" the child until some point and can do what they want with it. other libertarians will have even more differing viewpoints.
i didn't start my tech career after high school because every career advice i got was "all jobs going to india." could've had 10 more year's experience but instead i joined the military. ugh!
another easy way to get started is to install it in a VM. once you have the process down, you could try installing it to a secondary disk or partition on hardware.
take stuff apart and put it back together. install obscure operating systems. build a network and servers for just yourself. put multiple operating systems on the same computer. repair a broken laptop or phone. just fun things like that
