ETFs allow for liquidation any time during trading hours. Mutual funds typically only allow withdrawal once a day using closing marks. ETFs are also structured more efficiently for taxation purposes than mutual funds.
No: ETF decay is real and always has been. You're better off shorting an inverse ETF than buying and holding SPX.
edit: and shorting an inverse ETF has it's own problems, mainly what happens to your position if the market crashes - but that problem exists in any strategy.

This is bad advice.
Entering a short position requires paying interest on the borrowed shares, which may consume any decay you're collecting.
Short positions cap returns at 100% and have the potential for unbounded losses. Long SPY (S&P 500 ETF) produced returns of 280% since Feb 2009. Short SH (Inverse S&P 500 ETF) yielded 84% over the same period. In order to generate similar returns, you'd have to increase your position size periodically.
The long position also has the advantage of providing collateral, whereas the short position consumes margin.
You're going to have to explain that better. First of all, I don't think you can buy the actual index (SPX) but you could buy a future on it. Do you mean SPY? VOO? Second, I haven't heard of decay of unleveraged ETFs. And even for leveraged ETFs it's at least controversial to say it's a real phenomenon. Third, in what way does borrowing to short the index help you, given that you have to pay for the privilege anyway?
Keep in mind that SPY yield today is 1.9% — below CPI — so you are losing value even before paying tax on that income. If you are hoping for capital gains / equity risk premium to provide extra return, you owe yourself to read a bit about where we are in the economic cycle, current corporate debt levels compared to history, and to look at what happened in 2000, 2008, and last December and visualize going through that. To get passive income beyond the dividend yield you’ll need to be selling shares, not buying them. Consider the scenario, hopefully unlikely but historically demonstrated, that it goes down 50% at some point, or spends an entire decade with zero total return. US equities have been a powerhouse but it’s worth some careful research if you are looking for passive income.
That's dividend yield. If all companies stopped issuing dividends and instead spent the money on buybacks, you'd have a 0% dividend yield, but the same amount of money would be returned to shareholders without incurring a taxable event for remaining shareholders. Reinvesting dividends would allow for continued growth at whatever rate the ETF appreciated or depreciated, minus taxes.
> below CPI — so you are losing value even before paying tax on that income
All other things being equal, the value of your money is decreasing at the rate of CPI regardless of whether it's in cash or equities. Cash can be thought of as a bond yielding a return inverse to inflation, whereas equities are securities yielding a variable, unspecified return.
> where we are in the economic cycle
Determining this is difficult. Australia, for example, has not had a recession in 27 years.
> current corporate debt levels compared to history
Debt levels are at nearly all time highs relative to GDP (2000: 22%, 2008: 24%, 2019: 33%), but interest rates are also favorable for companies and close to historical lows (Investment grade OAS: 1.64%, High Yield OAS: 4.19%).
Trailing S&P PE is 20.72, which is at the top end of the regime from 1928 to 1990, but roughly average for the regime for 1990 to present.
I'd like to add that SPY yield if you invested today is 1.9%, but if you dollar-cost average invested over the past 10 years, your yield-on-cost would be much higher ~5-6%.
There’s also no natural law that says it needs to be stationary. The historical mean can just gradually rise. It can be like climate change. This is what makes markets fascinating — many independent agents evaluating the present opportunity set, acting on their internalized narratives and beliefs as well as data, with gradual turnover of the population of participants.
In a thread asking for options for present passive income (ie money coming in every month that you can eat with while you learn Python) it seems important to distinguish that need vs a long term investment strategy where you have money passively going out every month instead of coming in. One thing the market provides is a trade between people who have needs on different time frames.
VTSAX covers the entire market and has really low costs.
