We can clearly see that printing bitcoins is a stupid idea as all it results in is the complete inflation of the currency that is being printed such as USD. This has happened before after WW2 when Germany had a huge debt to pay back to the Allies, and the only way they could solve this was to print more money. This inflated the Mark so much that you needed a wheelbarrow full of money to buy a loaf of bread.

Maybe this is not the extent that things are happening these days, but it is sort of the direction we are heading to. The lovely thing about bitcoin is its capped supply limit, which will ensure that bitcoin retains its value while its popularity is growing at the same time.
