Bitcoin can't be money with a capped transaction rate.
Gold only maintains purchasing power due to being subsidized by central banks - there's no such thing as intrinsic value for a currency.
If those transaction rate limits are hit and the situation isn't fixed, then Bitcoin will disappear.
The transaction rate limits are fixable. The real problem is the inevitable centralization of mining. It seems that no one knows how to fix that. Bitcoin with centralized mining does not make any sense.
