No. They cost effort and time. Today money is thought out as an equivalent of effort and time but this is not politically correct.
The companies providing the equipment on which the experiments are performed expect to be paid for their machines. Equally important, if not moreso, the people performing the experiments expect to be compensated for their time.
Because of entropy, there is wear and tear on machinery, which must be repaired or replaced, and raw materials like fuel and chemical reagents get used up. Radioactive isotopes decay into inert and useless lumps.
So, yes, experiments do cost millions of dollars.
Again production costs money: that's a fact. Knowledge does not and should not.
Tell me, did your teachers teach you all you know gratis, or did they expect to be paid?
Did you study in a building that had to be maintained, repaired, cooled and heated?
Eschewing a full time job in favor of having time to go to class is a measurable economic opportunity cost.
Those elements and more are where tuition bills come from, and tuition represents the economic costs of gaining knowledge.
Sergio Aragones was once asked why he charged $40 for a quick sketch at a convention. He replied that the $40 wasn't for the 5 minutes it took him to do the drawing, it was for the years and years it took for him to learn how to draw in his distinctive style, and quickly and accurately enough to do so in 5 minutes without error.
But this knowledge was not always free. It was uconceivable to question some things in the past you know. Is it better know or then?
True.
OTOH, before IP laws, all creators had going for them was self-help. If you didn't have the money to safeguard your secrets, a competitor could simply take your ideas and make money on it himself, without incurring all the investment costs you had.
In every aspect, the advent of true IP laws means the difference between potential wealth and lifelong toil. A modern music performer can depend on the law to help him enforce his rights and thus his ability to make money from the songs it took him years of practice and 6 months of writing to create. His counterpart in previous centuries was simply out of luck if someone stole his song and performed it before the Prince before he did.
So, yes, it is generally better now.
