Overall very good summary and explanation why Bitcoin is already designed with resistance to attacks even of possible future Quantum Computers. Satoshi even explicitly mentioned this.
One weakness is point 5 which a common mistake to assume that there is a cryptographic puzzle to solve - it is not. It is a brute force approach to find a fitting hash with certain demand of leading zeros.Overall very good summary and explanation why Bitcoin is already designed with resistance to attacks even of possible future Quantum Computers.
