This fee thing fit dey avoidable especially, when your funds dey with escrow site already. The next thing na say, make the escrow dey offer those services like card as you talk. E go make people dey realise, the value of bitcoin no start from the value way dey attacked to 1btc, say with the #1k, you don transact with Btc and this fee thing no for worry, e go just be swap of funds between you and the escrow.
You dey correct that if bitcoin dey with escrow provider, fee no go dey there. But e depends on the type you dey use, you dey talk about custodial escrow provider. If na noncustodial, 2 of 2 or 2 of 3 multisig approach will be used, which go even take up more fee. But, you dey correct as na custodial service escrow provider you dey talk.
Waiting me dey think be say I still like the approach in which you will need to pay an address, it dey risky more than your opinion, but privacy go dey. As some platform don dey support bitcoin lightning, e make sense in my opinion. Litecoin transaction too make sense, e get a coin wey I like for such low fee which is digibyte, e make sense too, but no yet dey supported for many platforms. But your opinion to be an alternative na good suggestion because many people no even care if na custodial or noncustodial, but they just prefer there transactions to dey safe and secure.
