1) bitcoin CAN be created in unlimited amounts, in the form of alternate crypto currencies, because the alternates serve the exact (if not better) functions/purposes that bitcoin does. Sure there won't be more than 21 million "bitcoins" in the universe, but there can (and will if bitcoin is mass adopted) be infinite amounts of cryptos just like bitcoin. It is only a matter of time. In this sense, bitcoin is no different from tulip bulbs, granite rocks, etc.
blah blah blah
people use dollars, and you can repliate them as much as you like.
you can also make alternative bank notes that use the same protocols and technology. these are called pound, euro ruble, rand, yuan, yen, guilder, peso, boliviano, lev, pula. real, colon, kuna, koruna, krone, kroon, cedi, Quetzal, lempira, rupee, krona, forint, Shekel, rupiah, rial, Tenge, won, lat, kip, som, ringgit, denar, tughrik, matikal, cordoba
.. more blah blah blah.. cant be arsed listing them all, in short there are 180 official legal tenders of the world..
as for you comparing bitcoins to tulips..
what your analogy should have been was that bitcoin a tulip, and litecoin was a rose, and peer coins were dafodils, and feather coin was a sunflower..
which i would have then replied tulips can be reproduced unlimited thus proving bitcoins and the entire colony of altcoins are NOT flowers because although they're different 'strains' of cryptocurrency.. each strain cannot be unlimited reproduced.!!
bitcoin and the other colonies of crypto currency cannot be endlessly printed within their colony's (country/blockchain) thus cryptocurrencies are nothing like legal tender.
as for the gold analogy:
gold is its own element, its own features and benefits. you cannot passoff silver as being gold, you cant even pass off white gold as being the same as normal yellow gold. that are all unique.
same with crypto currencies.. you cannot say that litecoin is bitcoin, a litecoin transaction cannot be used on the bitcoin blockchain much like copper cant be used for the same as gold, without people seeing the differences,
although gold and copper are both brought into circulation the same way ( digging from the ground) although legal tender is brought into circulation the same way. they are all unique to each other. just like bitcoin and other altcoins.
so please try harder to understand bitcoins benefits over fiat and precious metals
