IMO PPG's comments added context.

LOL

I was adding detail and context to the quote I listed from jpalermo1964 which pointed out the high income tax rate in California. Other taxes exist in California because its citizens as a group think poverty should be addressed and reduced or ideally eliminated while being addressed through taxation.
As pointed out by cjpalermo1964 California is now exploring collecting more tax on out of state sellers in the form of income tax (personal or corporate). You need not agree or disagree with the why nor the noble intended target for spending the tax money, BUT one needs to understand the increase and spread of taxation will impact both sellers and buyers of stamps.
As commerce methods change, taxation follows behind changing as well. For decades, internet sales were not taxable unless certain conditions were met. Then a couple of years ago that was changed by a SCOTUS ruling and internet sales can be taxed by sales taxes. Can means may not must, but as some jurisdictions have decided to charge sales tax, that changes the playing field for all bidders and buyers of stamps in this internet age.
Other changes occurred due to the pandemic and working from home. Employees were taxed where they physically worked (e.g. at their office) but when they began to work from home and home was in a different state than their office, they stopped paying tax in the state of the office location. Some states felt a large loss of revenue and said no matter where you worked from home, you still were in the office location and need to pay office location based income taxes. States went to court and such taxing (income) of now out of state workers in the home state of their office was upheld. It is not much of a stretch for California now to find a nexus to start collecting income tax on out of state folks earning income from California.
Such have been considerations in the stamp hobby for years. Before the SCOTUS internet sales tax ruling, a state could only collect sales tax if the business had a physical presence in the state. Well, I like to buy from Siegel's Auctions. They collected sales taxes in their home state but were required to collect sales taxes in California when California discovered one of the Siegel principals had a vacation home in California and at times did corporate work while at the vacation home. So what? It causes me to have to pay sales tax on Siegel purchases when other folks don't raising my stamp hobby costs.
To Partime I ask, will you pay 10% more for a stamp just because you are buying it from me in California when the same can be had without that 10% premium from a seller in Nevada? If your answer is yes you would pay 10% more, then by all means, ignore the details as they don't matter to you. However, most folks would not pay a 10% premium to buy from California and that my friend impacts all of the sellers and buyers in the philatelic hobby.
Lastly poverty is a fact based numbers definition without regard to gender, age, skin, hair or lack thereof, citizenship, immigration status or any other definers currently in vogue to sort and separate folks. The ten dollar bill in a wallet remains a ten dollar bill no matter whose pocket has the wallet and if you only have a ten to your name you are impoverished--all politics aside.
The goals of the
eBay Vault I see as three fold, make more income for
eBay, reduce costs to buyer and sellers via elimination of certain normal costs such as taxes. Headquartered in California,
eBay did not pick Oregon, a no sales tax state, by accident nor whim.
