If buying steem power did not involve opening an account I don't want to buy a currency I don't want to then convert to SP, maybe.

If I could use an account I currently have (you know, old fashioned bank account) to transfer directly to my steemit account to power up, I would do so.

It is one thing to get a bunch of people like myself (non crypto types) interested. It's another thing entirely to get us interested enough to jump through those hoops.
