Sure, but if you don't know what all the ways are you'll be prone to "just follow instructions" and you may not notice that a few years apart your followed instructions regarding different ways of installing or uninstalling things and now your system is a mess
Becoming aware of different ways to do things costs time (to read about it and form opinions on things like which ones are/might be useful to you) and space (in your brain to remember these options and opinions). It's not necessarily bad, but it's a cost.
