To extrapolate further consequences from infinite liquidity:
options are useless. Any attempt to move the price by gamma squeeze just gets washed out with a larger amount of short selling. It's possible the hedge funds were taken by surprise in January 2021, but they're watching closely now and they won't let it happen again.
TA is useless. Sure we can look at short volume and options data and draw lines on a whiteboard. But any time we predict a MOASS they will just short sell more on that date and there won't be a MOASS.
How to MOASS? Audit the DTCC. The only way we win is if there is a short selling ban on GME. The ban would have to last for years and force all short sales to close without any opportunity to roll over the short by just shorting more.
