The cost thing is a dumb argument, as there are many more factors at play that result in a positive ownership experience than just accuracy.
Don't get me wrong, if a $2,500 Sako shot like sh!t then of course it would be a waste of money even if it were well made, but build quality, feel, and "presence" goes a long way.
They say the same thing about motorcycles, why would anyone buy an Italian Ducati when Japanese sportbikes are faster, more reliable, and less money? If your brain only thinks about practical things then sure you'll buy the Honda, but if you care about soul, emotion, and personality, you're willing to overlook a lot of things to get something that just feels better.
And such it is with the Tikka vs Savage, or a Norinco vs Daniel Defense, or a Ruger SR9 vs Walther PPQ. Sure you can spend less money and end up with a similar grouping, but if you can afford more, generally you will be happier with spending more. Not just for the sake of lighting money on fire, but the build quality really is better. Your hand will feel better on the grip, the action will be smoother, the construction will be better and you'll see that when you're taking it apart to clean it.
If you only care about accuracy then sure buy the cheapest thing you can to make a grouping, but that should only be one factor in your purchase. If you only have one factor in your purchase, then I almost feel bad for you that you're missing out on so much more of what shooting and pride of gun ownership can offer you.
Good luck explaining to your buddies why 4th place in comp isn't so bad because you soul and emotional needs were being satisfied.
Yeah but but its got personality...
