Yes, that is a good idea. I reached the conclusion I'm going to sell interested people bitcoins myself. Minimum withdrawal from Stake is 20,000 satoshis and there is a fee of 7000 satoshis. For larger transactions that fee is fine, but if they want to acquire a small amount, I can also make the transaction from freebitco.in platform, paying only 520 satoshis on fees (slow withdrawal).
The point now is the receiver wallet... I know people in real life who invest in
BTC and use only Binance to store their coins, so it's indeed the first option for the layman due to the accessibility, and they don't seem interested in self-custody. Moreover, it's out of my control if they prefer accessibility over safety, after all it's responsability of each adopter to take the possible consequences for their decisions. They will decide doing the don'ts or the dos, as they wish.
My advice is that a hardware wallet is purchased, as that is the method I use and think it's pretty simple, while being safe.
I also know of some individuals who know about and actually own crypto but don't know about self-custody, about hardware wallet, about Lightning Network, even cheaper fees with SegWit, and so on. What I'm saying is that it might not be about them having the freedom to choose which they prefer. To some, it might simply be about lacking education or awareness. And since you're in a position to educate them, I guess that must be included. At least they're aware of the options and the risks involved when they make a choice.
If it's simply a demonstration that you want, you don't have to require them to have a hardware wallet. As you mentioned, the amount is $1-$10. An open source non-custodial wallet is enough.
