Personally, I think this is possible because it is only an increase of 10 times from the current price. When it comes to Bitcoin, anything is possible, and in 3+ years to go from $10k ->$100k is something that is quite realistic.

What we need to ask ourselves is what would cause such a price increase, because it will not happen by itself very likely. Can such an increase in price be caused by small ordinary people who will invest in BTC in the next three years, or it all depends on the institutional investors? If they wait to SEC approve ETF, perhaps the real question is whether this is the next big thing that will launch BTC to the moon.

Still I would disagree that governments have no instruments to bring price down, or to even make cryptocurrency completely illegal. All they need to do is to shut down all crypto exchanges, and declare crypto transactions illegal+completely destroy any legal connection which banks have today with crypto.
