When you purchase Bitcoin and hold it in on-chain you're taking part in the current UTXO state
Discussion
What is this story that there is not enough UTXO to serve the entire world population? If you have a UTXO of 1btc, isn't it possible that you can actually 100mil UTXO by sending 1 sat to 1 address? Isn't it in theory, 80 bitcoin can create up to 8bil addresses of a single sat?
