I'm assuming you are concerned about UTXOs and how the crypto analytics companies can trace your BTC. I highly recommend looking up on YouTube, check out Matt Crater from Bitcoin University (has a course on that) and Sparrow wallet mixing service.
Essentially, you can purchase everything normally like everyone else does but use a mixer to anonymize your BTC on Blockchain before moving safely into your hardware wallet.
Definitely get a cold storage wallet.
I just hope we get little bit more traction than what we have right now, especially with Piracy. I would think that there should be more folks who are interested in piracy but it's not as active and big as I wanted it to be. I actually enjoy passing by once every while to learn about something new and exciting that people are trying out.
