Define “Internet” to answer your question more meaningfully.
Are you counting cached copies of data (Cloudflare etc), or only the original copy? Only the source data or the data copied on the receiving end (webbrowser etc) too? Data at rest on a computer hard drive or data being transmitted or both? Are you only including world wide web (websites) or any data (gaming, streaming, fileshare). Humans or bots or both? Public web or dark web? Any computer physically connected to a network or only those data accessible publicly?









To be fair the very idea of value of money is “imaginary”. Even a bank note is nothing more than a promise.
The value of a stock is derived from the trust that someone will trade you for it. If the trust goes away, so does the value.
Similarly, the value of a bank note is derived from the trust that someone will trade you for it. If the trust in a bank (bank run) or government (scarce money supply, solvency) or economy goes away, so too will the value of money, i.e. inflation.
Even comodities and tangible goods have “imaginary” value, because these things can be under or over produced, which in turn changes how likely someone might want your good.
That being said, the degree of imagination needed to trust the value of trade varies, and stocks are definitely close to the top of the imagination tree.
