If you won the lottery on crypto then you aren't going to be destitute in retirement. Pay the capital gains and enjoy your wealth.
Similarly, if you are a high earner and can afford to take advantage of things like the megabackdoor then you aren't going to be destitute in retirement. Pay the capital gains and enjoy your wealth.
The purpose of tax advantage retirement accounts when originally introduced by ERISA was to give employees of private companies a safety net in cases where their pension defaulted or when a pension wasn't offered in the first place. There's really no mention of it being specifically for people who are destitute or would not otherwise invest. Traditional IRAs are available for everyone, even high earners, no gatekeeping.

Traditional IRAs are taxed on withdrawal and function much like other investments.
Tax breaks exist to promote prosocial behavior. Getting people who are struggling to be able to afford to save for retirement is good for society. Giving people who made it big with a lucky gamble a benefit is just good for that individual.
This is no skin off the back of the wealthy. They'll find another trick and life will go on. For those of them that actually care about "normal" Americans being able to do the same thing they did, it feels a little wrong that it requires an ever increasing amount moving parts and money to do what they did.
it is overly simplistic in USA - real people lose their "wealthy" status every day. You think a "wealthy" restaurant or bar owner is having a good day in 2021?
this class-baiting comes from the previous century, and IMO detracts from real problems right now
I don't entirely understand what you're construing as class baiting. You don't have to have any contempt for the incredibly wealthy to acknowledge that they're going to walk away from this with extremely minimal losses, while your average person with a Roth IRA account won't be able to use it for starting or supporting their own business.
The default is taxable accounts. Things like IRAs and 401ks are exceptions carved out to encourage the population to invest so that they don't end up eating cat food at age 80. People building huge fortunes in their IRAs isn't achieving this goal.
