Rebuilding Taiping Continent is actually a very troublesome matter. Many people don't want to tackle it even knowing how profitable it can be once completed.
Firstly, the smuggling hub in Dog Town can't be eliminated. Doing so would offend countless people, and you wouldn't even know how you'd die. Lin Miao was already encountering assassination attempts from Soviet Petrochemical and the Cubans as soon as he entered Dog Town, and it was only his tough luck that allowed him to survive. Anyone else would've been a rotting corpse by now.
Next is the economic dispute. Every building on Taiping Continent's land is owned by someone, whether or not it's an unfinished project. Legally, these companies hold the ownership of the land.
If you want to rebuild, you must sign a new contract with the party in charge. Otherwise, tampering with their properties or land is illegal. Even if you know exactly how the house should be built, the other party can still sue you and demand a lot of money.
