Based on this paragraph from "HF20 Update: Operations Stable"

Blockchain Subsidized Account Creation

The RC system has delivered the ability to create “blockchain subsidized” accounts, which means that it now has uncapped the scalability of the platform’s account system by introducing the possibility of account creation into the quadrillions of accounts. Prior to HF20, the hard limit of accounts was in its best case defined as the total available STEEM supply divided by the amount of STEEM spent to create an account. Now, because the rate of subsidized account creation is determined by the witnesses, Steem can admit as many people into our community as we desire, as long as the witnesses agree that it is safe to do so.

1. uncapped - I do not know a lot about business, but when reading this in context, it does not sound good, to me it sounds like limited edition, but we get to keep making more and more as long as people want to buy. So not a collectable item for value growth.

2. introducing the possibility of account creation into the quadrillions of accounts. That pretty much like I said kills the individual ability for growth. Who would "buy" at your price when someone with 30 times more accounts undercuts your price and are always able to undercut the price of the competitors.

3. we desire, as long as the witnesses agree that it is safe to do so So out of the top 20 witnesses, one individual can alter the make up at whim, so we desire means diddly squat.

But like I said, I am not a businessman, just a user. Also RC's have been removed from the consensus loop, so to me that just adds more risk.

And part of the paragraph from HF20 Update: Restoring Continuity, that I still have issues with, this was put out by the steemiblog, I have been told that the we are the witnesses,

Due to the fact that many components of the RC system are non-consensus, we can continue to adjust the resource pool budgets, track trends, and adjust charges incrementally over time so that we can meet our third goal of moving us toward sustainable pricing of blockchain operations.

so currently and in the future there is no price stability guarantee for RC's. Like all taxes, once implemented they never go down. From steem.io front page:

Faster than Bitcoin and Ethereum, with no fees

Running a rewards-based decentralized social network required new advances in blockchain technology. Steem is a next-generation blockchain, uniquely designed to run real-time applications with near instant, fee-free transactions.

Steem has been battled-tested over the last 18 months, already processing more transactions per second than Bitcoin and Ethereum.

So I don't think even if I was able to I would at this point buy an account token
