You have completely failed to understand the security model.
"Supply" is irrelevant, there's one Bitcoin and one monero - a singleton which is divided among everyone who holds it and diluted at a specified rate. Monero has tailings, infinite inflation, infinite dilution of existing holders.
Monero doesn't have a 0.3 mb block size, the block size follows an algorithm and operates on a sliding scale. There is no effective minimum or maximum monero block size.
Monero's privacy is a double edged sword. It allows exchanges to routinely rehypothecate it / print it for free.
The point of Bitcoin is **total separation of state and money**, individual sovereignty, the emancipation of humanity. Transparency is critical to this, the way to deal with psychopaths is to shine a bright light on them.
The point is to force governments into an even playing field like any other organization in the free market, it begins with the axiom of resistance - the intention of Bitcoin is not to provide a way for us to not hide from governments like rats and cockaroaches.
Privacy is not an absolute good or bad thing, it's a tradeoff. Monero level privacy is designed for a world where we have accepted that we cannot overthrow tyrannical powers.
Under a Bitcoin standard, transactions are not private because that would give corrupt tyrannical powers somewhere to hide and bankers something to rehypothecate. Psudonymous transactions are a tradeoff that under a Bitcoin standard benefits the individual more than it benefits large groups with pooled resources.
The "final boss" of a consensus layer attack is to dominate the hashpower and mine empty blocks to make the network useless. If governments feel threatened by monero, it's multiple orders of magnitude cheaper for them to kill it with this attack than it is to kill Bitcoin.
Reality meets hypothetical.
