If bitcoin achieves the physical form like credit/debit card then I am sure it will get more popular and more people will start using it as people have more faith in something that they can hold physically.
It would surely reach to that point but it needs quite a lot of time to reach there as before that it needs to get adopted by resources in physical because without that people wont believe it and wont be ready to use it like how they use fiat.
just a concept, or dream : the smart card wallet have a secure protection, every one can see the wallet addres and the balance of bitcoin, but the privekey only stored by bank. in this case only bank can move the bitcoin, but the pisycal of this wallet is legal like normal money,
i hope in future bank can produce it
