Giving answer the Stedsm style:
1: Exposure to Bitcoin-Specific Scams and Fraud.
Depends on the level of security one keeps to secure their Bitcoins from such scams and frauds.
2: Black Market Activity May Damage Reputation and Usefulness.
If I'm not wrong, even Godl (gold) is involved in such activities like smuggling and/or stolen bars/pieces being sold in black markets.
3: Susceptible to High Price Volatility.
Guess that's why everyone's here for - making profits with their asset.
4: No Chargebacks or Refunds.
I believe this might be a drawback, but it's also good to stop misuse of the system and as well, it tests the concentration power of the sender as they're the only ones who will be responsible for any such false sends unless their private key got hacked and everything's swiped by hacker.
5: Potential to Be Replaced by Superior Cryptocurrency.
Waiting for this since past 8 years, eh!
6:Environmental Ills of Bitcoin Mining.
There have been projects I call as green mining where people use solar power to power up their mining equipment. I know that it's not too much used and not even able to cope up with network's requirements to smoothly process everything as the electricity levels needed in it couldn't be matched many times.
7: Bitcoins Are Not Widely Accepted.
Due to restrictions levied by governments in various countries, its adoption and growth levels have declined to a much broader level.
8: Wallets Can Be Lost.
See my reply to your 1st reason that you stated.
9: Risk of Unknown Technical Flaws
If you know any technology that comes without a single flaw, please do let me know.
10: No Physical Form
There are many digital wallets through which we pay our Fiat itself, and Bitcoins, if seen as assets, need not to be physical as the beauty of it is being transacted digitally.
Which of the following disadvantages are you afraid of and how do you think it can be resolved
I'm quite happy you're so concerned about the challenges Bitcoin is facing, but everything takes time to get resolved and devs are already doing what they are able to do at their best and tackling these challenges, not to let any such vulnerable situations occur.
