It actually does matter, troops and tonnage carrying capacity matter a great deal when you're trying to get as many troops on a beach and on captured ports as possible.
Tonnage is simply the first part of the equation, and a bunch of fishing boats and civilian ferries aren't exactly purpose built amphibious landing ships.
The Taiwanese military isn't going to wheel out SPHs and towed guns and shell boats when China has air superiority over Taiwan and Chinese drones do to Taiwan what Turkish drones did to Russian columns in February 2022, or Syrian columns in 2019.
China has to
gain air superiority first. Taiwan does in fact have an air force. Ukraine has shown that it if perfectly possible for a second tier power to hold off a first tier power with tenacity and ingenuity in the air department. And Taiwan is far better equipped than Ukraine.
The moment a Taiwanese anti ship missile is launched it gives away it's launcher and that launcher gets targeted.
Any counter battery fire would have to get through air defenses.
How fast can Taiwan mobilize?
Fast enough. Any major troop build up close to the island will be spotted weeks or even months in advance. There are only a few months out of the year when an invasion is even possible due to the weather patterns in the Taiwan Strait, and Taiwan has had decades to prepare. They will will have plenty of forewarning prior to an actual invasion.
What happens if the military commander centers, communication nodes and arms depots are levelled by Chinese hypersonic missiles in the first 5 minutes?
All important military facilities will be hardened against just such an attack. This is even assuming China has the hypersonic missiles to launch such an attack in sufficient numbers to matter, or that said missiles won't malfunction or fail to accomplish much even if they are launched. Hypersonic missiles aren't some wunderwaffe. As the Russian invasion and use of their own missiles showed, they are, at the end of the day, just missiles, and I doubt China has a lot of them.
What happens when cell towers and the Internet doesn't work on Taiwan for a few hours or even days during and after D-Day?
Not sure how much it would matter is civilian internet goes down. Military intranet systems will be hardened against attack.
Remember, the average Taiwanese citizen in unarmed and actually doesn't like or actively despises the military....
The average Taiwanese male has already done his mandatory service and can be quickly called up in the event of an attack. And there's no indication at all that the average Taiwanese despise their military which would be irrelevant regardless in the event of an actual attack.
That's not correct, Russian double agents were mostly oligarchs and the like, very few were in the Ukrainian military or Intel services and the ones that were were lower level and maybe a few mid level types
And there's no proof whatsoever that China's double agents, assuming they exists, aren't basically similar figures. Once again, Russia's double agents proved to largely be irrelevant, and most of the money was pocketed by Russia's own agents due to massive levels of corruption, which China also suffers from.
The oligarchs told Putin exactly what he wanted to hear, just like Iranian defectors to Iraq in 1979 did with Saddam.
And China's generals and bureaucrats tell Xi Jinping exactly what he wants to hear, because nobody wants to risk their career telling him something he doesn't want to hear.
