I think if bitcoin was created and had a physical form it is likely that bitcoin would not be as popular as it is now. Because of course its use will be slightly different from Bitcoin which is digital. Apart from that, spreading it will definitely be more difficult, because if Bitcoin has a physical form, it is certain that if someone wants to own it (buy it), they will definitely have to look for a shop or market that sells Bitcoin. But the problem is that bitcoin means have to have branch stores all over the world to make it easier for everyone to buy bitcoin. Meanwhile, if it means that in each shop, it means someone has to look after it, and also the shop building means someone has to build it. In this way, it is possible that Satoshi cannot be completely anonymous, because after all he is the one who will definitely manage everything, including the shop and also the workers in the shop.

Apart from this, if bitcoin had a physical form, I am sure it would be easier to manipulate or bitcoin would be vulnerable to being turned into a realm of fraud. Because there could be a handful of people who create fake bitcoins and sell them at the same price as bitcoins. Then what is even worse, bitcoin will definitely become centralized and not decentralized. Because that way, it is certain that every bitcoin coin that is printed must have a center and even though the number is limited like now, bitcoin is still seen as having a center.

So in essence, if bitcoin is made in physical form, there will be values lost from bitcoin. Like the decentralized system will disappear. The blockchain system will also disappear. And anonymity will also be lost.
