Off course. Taiwan is a whole different scenario to Ukraine. Taiwan is not a UN-recognized sovereign country unlike Ukraine. Taiwan is Chinese territory. It is a civil war, hence China has every right to escalate the fighting to total war, to take back a rebellious province. There are no if or buts. No country would willfully accept the breaking up of its own territories. If the free world can accept Ukraine's complain about the separation of Crimea, Donbass, and Luhansk, why then do they interpret it differently for China?
Any country that interferes to aid the Taiwanese separatism can be considered an act of war with China. This is what America and the free world have so much trouble understanding. Imagine if California decides to break-away from the USA. And China or Russia aids California in a war of independence from the USA. Would the USA interpret that as an act of war? Off course it would!
Now the biggest problem to a unification war is really the economic/financial war between the US-led West and China, on top of the hot war. Right now, the people in the West who are interested in Taiwan/Mainland issue, is increasing confident in the idea that they don't even need to commit their forces in direct military confrontation with the PLA, and rather resort to econ/financial war instead.
In this case, they will happily see Taiwan turned into a "80s Afghanistan" for China, in which it will drain Chinese military and other resources in creating a conflict zone which East Asia, which will drive global capital out of Asia and back into the West, all the while the West wage economic war on China. This is the real concept.
This is why, in case of Taiwan, the PLA will increasingly realize that, in a realistic unification war, their main goal will NOT be how well they can conquer the island, but rather how fast they can absolutely destroy the effective fighting forces on Taiwan. Once that backbone of resistance is broken, the PLA will be able to allocate their resources in fighting the economic war with the Collective West.
The island will then just be more of 维稳治安战 (stability/public-security war), with horde after horde of militia organized and commanded by the PAP moving into the island, as well as civilians moving out of the battered island.
There will be no stalemate like Ukraine, it will be annihilation of the separatist's organizational structure, or complete capitulation and surrender of the separatists' entire leadership structure.
