Like you said, as long as you don't sell, you should be good to go and the only concern would be inflation. Now, here's how I like to look at it: It would be a lot worse for people that do not own bitcoin because whatever fiat money they have get destroyed by inflation but with bitcoin, you still have upside potential (probably downside potential too if entry is super high). So Bitcoin actually gives an edge vs other people that don't use or hold Bitcoin.
Taxes and inflation will forever be a thing. Likewise Bitcoin.
There are always going to be ways to deal with Bitcoin "under the radar" and avoid taxes. Even though that might not always be possible, there are still ways to avoid the increasing taxation, which the OP mentioned and is frustrated about. Also, I agree with what you've said: we should currently worry about inflation more than a hypothetical increase in taxes, which would counter your gains from Bitcoin. The increasing living cost is a far more complicated and worrying issue that would actually hinder your available income, thus also the real value of your Bitcoin.
