The reason I have been deciding not to get a hardware wallet is because of the data leak issue, once the data is given to those companies, then it can be hacked and leaked to hackers just like the Ledger. Data leak can happen to any company, the company can even sell the data or give it out to another party.

You are only holding bitcoin according to the OP, if holding only bitcoin, then I still see no reason to get a hardware wallet, wallet on airgapped device is still the best choice for privacy, or to just buy directly like you have mentioned in the OP, but BitBox01 is never a good option because of the reasons Shiftcrypto mentioned and it is old version. I have one thing about the latest version which BitBox02, how it supports Address Ownership Proof Protocol (AOPP) which is against privacy.

If you can have a good idea about how this can work, you can read this suggestion:

But this should be well thought of before buying hardware wallet, especially using fake name which I think is not advisable because of clearance. But in my opinion, I have thought of many options and I prefer wallet on airgapped device.

You can just buy another laptop that can do the task for you, make it airgapped and have another cold storage on it which is far better than going through all the stress of buying hardware wallet.
