Yes, of course there should be a "quid pro quo".
If the government takes half your earnings in income tax, NIC and VAT, the individual payer is not taking anything from society (by working and creating wealth he is indirectly benefitting society) and is getting nothing in return. There is no quid pro quo.
With taxes on land values, you are paying for what you get from society, the benefit of location values - that's your "quid pro quo" right there. It is each individual's choice how much and what value land he wishes to occupy, it's an entirely voluntary tax.
Everything else the speaker says is an outright lie anyway - for example, Australia, NZ and Canada have much higher residential property taxes than the UK. Valuations and enforcement is easy - it's like the old Domestic Rates. And so on and so forth.
