Interesting that two of the three examples you give here are things that are highly regulated, where the government has stepped in and said that "no, it isn't okay to just sell people anything they'll agree to buy."
People used to have their choice of banks and bank notes... and it was a disaster. The government stepped in and regulated things, removed some of the worst choices, and now it is better.

The SEC restricts choice by delisting stocks which are deemed unfit for purchase.
Really, the government regulates all sorts of things without people going around complaining about a lack of choice. There is no-one crying out for untested pharmaceuticals at the moment, but you can bet that if it was a currently unregulated field, we would have conservatives fighting for their right to sell and purchase unknown purple liquids for the elimination of assorted ailments.
