(Question) Are dementia insurance and caregiving insurance essential for retirement planning?

I am single and have no plans to get married.

These days, when you watch TV, there are many talks about dementia insurance and caregiving insurance.

Thinking about old age makes my heart feel a little heavy. Living healthily and long is like a dream, but I also worry about uninvited guests like dementia coming my way. Especially these days, when I hear stories about dementia patients and their families on the news or documentaries, a creeping anxiety of "Could it happen to me too?" starts to rise. That's why I began to wonder whether dementia insurance or caregiving insurance is truly essential.
Even when family members take on caregiving themselves, the time and emotional burden are enormous. The government's long-term care insurance for the elderly only provides 3 to 4 hours of support per day for those rated 1 or 2, which honestly feels incredibly insufficient. Seeing this reality, it seems quite wise to prepare in advance through insurance.

But, I wonder if it's really necessary.
The monthly premium for dementia insurance is around 50,000 to 80,000 won, but even if you sign up in your 30s or 40s, it could become a burden in the long run. Moreover, the conditions for receiving benefits can sometimes be quite strict. Dementia diagnosis is based on the CDR (Clinical Dementia Rating), but some policies do not cover mild dementia (CDR 1-2). If you cancel the policy midway, the refund amount may be less than the premiums paid.
The government's Long-Term Care Insurance for the elderly has recently been improved so that even patients with mild dementia can receive benefits under Grade 5 or Cognitive Support Grade. Additionally, it might be possible to some extent to prepare through disease-related disability riders on existing life insurance policies. Looking at these options, I started to think that dementia insurance might not be absolutely necessary.
