I believe it can, but not for the reasons you mention, which are more technical in nature, but because more and more people are going to realize the value of bitcoin. People are not aware that saving in dollars means losing money, supposedly 2 or 3% per year, but it is closer to 7 or 10%. In this regard, bitcoin wins hands down. In addition to the ease of being able to transfer it without censorship and the difficulty of confiscating it. Those with money will increasingly seek out bitcoin, while reducing their exposure to fiat currencies to a minimum.
