Not so much over time, but all at once or over say a few days.

Before that person can do that... they have all these other tools they need to learn (robosats, what TOR is etc)

And then they're meeting a stranger (assuming they find the posting on Robosats in their area for cash) to exchange thousands in cash.

To go from owning 'no Bitcoin' to doing this is... kinda a big jump imo.

And assuming it's a 'wealthy person' who's doing this weekly or monthly it's going to take quite a bit of time as well, and they want to do it safely too.

For one off buys or occasional buys it's not a big deal... but regularly I'm not sure it's the answer. I wish we could do more
