Society has deemed it "ok" for a real estate transaction to take days or weeks to process and mountains of paperwork, probably because it is done so rarely in an average person's life. But stock trades are expected to be done quickly in minutes or even milliseconds with high frequency trading. It just isn't feasible to inject government paperwork in the middle of a transaction. Wall Street would revolt if they even tried.

Nah. Look up the SEC’s reporting requirements, specifically form 4. The paperwork requirement already exists.

high frequency traders dont have a right to a business model.

if they want faster trades, they can take full liability for what they own
