Sharing is more than easy and natural, it's good. Sharing is so important to civilzations that early ones developed writing systems to facilitate it, and later ones have been improving it ever since. Reading and writing used to be only for the nobility, for the practical reason that educating everyone was more expense than was thought worthwhile, though this was also correctly seen as an excuse not to educate the masses. Words were terribly subversive, best if the people can't read them. The pen is not mightier than the sword if no one can read. Democracies changed that, deciding that 100% literacy was a desirable and nearly obtainable goal.
Now here we are today, and what are our supposedly democratic governments doing? Siding with those who think they have a right to lock away knowledge, those who think the worthy desire to compensate artists justifies all kinds of monstrosities and public expense, and that fair compensation can only be done through Holy Copyright.
Sharing should be encouraged. By everyone.
