If you identify the characteristic of Bitcoin (fees) that makes it possible for it to resist government censorship, it becomes clear that it is not impossible for Bitcoin to be co-opted by governments.

No one can predict with certainty how much governments will spend in an effort to control majority hash power, nor how much will be offered to miners in fees to overcome censorship by majority hash power, nor the extent to which honest miners will be enticed by these fees to take on the risk (of capital and legal liability) of mining a heavier chain.
