A common excuse, perhaps the most common, given for this is to "keep up with the times". This is tantamount to "Keeping up with the Joneses". Which is also a very common excuse we see given for wanting needless change. For example, see this election cycle's focus on how other countries are addressing issues and proclaiming that the U.S. should change it's ways to match those of the others countries held up as the example.
It boils down to doing what is popular, sometimes easier, instead of a more appropriate way that may be older or less popular. A phrase I like to use a lot myself is to "Work smarter, not harder." While this is good advice in a great many things, it can sometimes backfire when the "harder" is meant to be there. At those times, we just need to suck it up and get it done because in the long run, it is the best or "right" way to accomplish said task.
I think for most libertarian minded people, this amounts to what we call "Common Sense". There is something called the "Serenity Prayer" that goes as follows;
God grant me the serenity to accept the things I cannot change, the courage to change the things I can, and the wisdom to know the difference. Reinhold NiebuhrReligious connotations aside, this is a great example of knowing when one should change and when to accept that change is not what is called for, but acceptance instead.
In the typical "Progressive" view though, everything should be changed simply because it can be to accommodate people who are trying to avoid rising up to a challenge or, goodness forbid, having to meet expectations of us.
There are a number of things that can be changed with little to no real consequence because new technology becomes available or because a situation has irrevocably changed that forces adaptation. The change either had to happen anyway or it can have a satisfactory result in a variety of ways. This is the case for perhaps the majority of things we deal with in life. There is more than one way to do something and as long as we meet the "do what you want, just don't get any on me" philosophy, all is good.
However, There are times when things are best done a particular way and using any other method is not as satisfactory in results. Sure, it can be done, half-assed, as it were, but if it's meant to accomplish a specific result, then the half-assed way just won't cut it and we need to step up and get it done the right way.
The "Conservative" view would have traditional means and methods followed simply because "That's the way it's always been done". Also an unreasonable position because it too would deny the times when change is warranted or harmless.
As a beekeeper I can tell you that a great many things in beekeeping fall into the "harmless" differences anyway. Ultimately, the bees don't give a rat's patoot how a hive box is painted or what type of hive box you put them in. Bees will do what their natural biology and behavior dictates them to do. If it bothers them enough, they will leave. Which throws out the Vegan view of beekeepers holding bees as "slaves". Slaves can't escape. Bees come and go as they please whether the beekeeper likes it or not.
In a very few areas, directly related to bee biology and natural behavior (those things they are compelled to do through genetic memory and learned through situational adaptation) beekeepers will find there are few things they can change to suit the bees. For example, a hive must provide defensible shelter and be able to maintain a dry environment. if it is or becomes indefensible or weather invades it easily, they will "Abscond" meaning that all the bees just up and leave for greener pastures. Not a goodbye note to the beekeeper or anything. So, whether we beekeepers like it or not, we MUST provide a minimal acceptable hive to the bees or we won't have bees very long. That means we have to do a certain amount of work or expense to get a hive that meets those minimum demands.
Sure, I could slap together some sloppy job of a hive but if it gets leaky or allows predators to easily invade then my desire to go the "easy" route gained me nothing at all.
Sometimes, we just need to do things they are supposed to be done.
