The fact that Bitcoin price is increasing doesn't mean that it isn't a suitable P2P currency. However the difference is that it is a better currency for larger volumes of transaction in cash.
Although Satoshi's original dream was a simple P2P transaction system, we can arguably say that the result of Bitcoin gaining adoption and value was actually quite inevitable given special factors like decentralization, POW and even halving.
Bitcoin was initially designed as P2P electronic cash. The fact that now people are using it as a store of value has to do much with the currency's deflationary mechanism. With high fees and slow confirmation times, we shouldn't expect people to change the way they use BTC anytime soon. Now with "Wall Street" in the game, things got worse.
What I care about is Bitcoin's decentralization. If institutional investment companies amass a large portion of the circulating supply, BTC would be doomed. Even if economic holders don't determine network consensus (only miners). These entities can influence the direction of the Bitcoin project with their money. It's like moving one step backwards. At least, the code is open source. With many forks around, Bitcoin's original ideals can be preserved for generations.
