Monetary transactions are enabled by internet and miners equipment, not by Bitcoin.
The internet alone, by itself, does not enable monetary transactions.
What do you think pays for the mining infrastructure?
Transaction is an instance of buying or selling something. Of course, the internet alone does not enable the buying or selling of something, but what that has to do with the topic at hand?
Because you stated above that transactions are enabled by the internet and miners.
Obviously the internet by itself can't enable transactions, so in this case miners are required.
But what do you think pays for mining?
(spoiler alert: Bitcoin does. No native token, no mining, no permissionless monetary transactions via the internet)
To repeat: The utility of cryptocurrencies such as Bitcoin is monetary transactions. Whether Bitcoin is overpriced or undervalued is a different question, of course. But if you accept that banks, credit card companies and money transmitters (and by extension their respective stocks and bonds) have utility, you also have to accept that cryptocurrencies do. Everything else is just cherry picking.
