Can a Taiwan Province spouse go to Thailand without an ID card now?

yes. However, the following conditions need to be met:

1. Holding a valid passport: To go to Thailand, you must hold a valid passport and ensure that the passport is valid after the return date.

2. Obtain an entry visa: If you plan to stay in Thailand for more than 3 days, you need to obtain an entry visa for Thailand in advance. You can apply through the Thai Economic and Cultural Office in Taipei or the Thai Embassy in China.

3. Prepare other relevant documents: As you can't provide your ID card, you need to show other supporting documents to Thai Customs, such as marriage certificate and household registration book, to prove your identity and relationship.
