Paintings can also be endlessly replicated, all you need is some frame, cloth, paints, brushes, etc.
Peter Paul Rubens was even involved in replicating his own paintings. Yet after his death his paintings mostly appreciate in value.
After the last bitcoin gets mined in a hundred years or so, the available bitcoins will only gain in value, even if just to be shown in museums as an example of an ancient cryptocurrency.
There is some value in simply being first in doing something in a certain, very specific way, of doing something and in being first to popularize that particular way of doing that. When compared to Rubens' paintings Bitcoin has an advantage of being self-authenticating and cheaper to transport.
Exactly. When you make a copy of something it is not as valuable as the original and only affects the value of the original marginally. The more copies of the original are made, the less valuable each additional copy becomes, however the cost to copy will remain the same.
As people create additional scam coins the expected value for the dev will be lower for each additional coin that is created while the cost to create each additional coin will remain the same (or potentially increase due to higher demand for resources needed to create the scam coins)
